If any damage to the protective coating on the metal has occurred, repair the damage before laying the pipe. Lubricate the gasket and the inside surface of the bell with an approved lubricant (flax soap) which will facilitate the telescoping of the joint. Tightly fit together sections of pipe and exercise care to secure true alignment and grade. When a joint of pipe is being laid, place the gasket on the spigot ring and enter the spigot end of the pipe into the bell of the adjoining pipe and force into position. The inside joint space between ends of the pipe sections shall have an opening within the tolerances as recommended by the pipe manufacturer. No "blocking up" of pipe or joints will be permitted, and if the pipe is not · uniformly supported or the joint not made up properly, remove the joint and properly prepare the trench. After joining, check the position of the gasket with a feeler gauge. If the gasket is out of position , disassemble the joint and repeat the joint laying procedure . b. For interior welded joints, complete backfilling before welding. For exterior field-welded joints, provide adequate working room under and beside the pipe. 2 . Exterior Joints: Make the exterior joint by placing a joint wrapper around the pipe and secure in place with two (2) metal straps. The wrapper shall be 9" inches wide for pipe 36" and larger, and 7" wide for smaller pipe, hemmed on each side. The wrapper shall be fiberglass reinforced or burlap cloth, with lengths encircling the pipe, leaving enough opening between ends to allow the mortar to be poured inside the wrapper into the joint. Fill the joint with mortar from one side in one ( 1) continuous operation until the grout has flowed entirely around the pipe. During the filling of the joint, pat or manipulate the sides of the wrapper to settle the mortar and ex pel any entrapped air. Leave wrappers in place undisturbed until the mortar has set-up . 3. Interior Joints: Upon completion of backfilling of the pipe trench , fill the inside joint recess with a stiff cement mortar. Prior to placing of mortar, clean out dirt or trash which has collected in the joint, and moisten th e concrete surfaces of the joint space by spraying or brushing with a wet brush . Ram or pack the stiff mortar into the joint space and take extreme care to insure that no voids remain in the joint space. After the joint has been filled , level the surfaces of the joint mortar with the interior surfaces of the pipe with a steel trowel so that the surface is smooth. Interior joints of pipe smaller than 21" shall have the bottom of the bell buttered with mortar, prior to inserting the spigot, such that when the spigot is pushed into position it will extrude surplus mortar from the joint. The surplus mortar shall be struck off flu sh with the inside of the pipe by pulling a filled burlap bag or an inflated ball through the pipe with a rope.

A SULFATES, CHLORIDES AND pH TEST RESULTS .......................................................................... B 1 EXECUTIVE SUMMARY HVJ Associates, Inc. was retained by Freese and Nichole, Inc. to provide geotechnical investigations for Harley Avenue Street reconstruction From Rip Johnson Drive to University Drive in Fort Worth, Texas. This project involves providing pavement design recommendations in accordance with City of Fort Worth, and design guidelines for the foundation of Junction Box. The purpose of the geotechnical investigation is to perform borings at the site, perform laboratory tests, and provide design guidelines for the proposed pavement and junction box. Subsurface conditions at the site were evaluated by drilling and sampling three 15-foot and one 20- foot borings, below the existing ground. A brief summary of the investigational findings consists· of the following description: · 1. The subsurface soils at boring B-1, consists of stiff to very stiff clayey sand with gravel till 4 feet, followed by very stiff high plasticity clay to a depth of 11 feet, followed by sandy gravel layer till 14.5 feet, and 0.5 feet of weathered limestone to a maximum termination depth of 15 feet. 2. The subsurface soils at boring B-2, consists of stiff to very stiff high plasticity clay to a depth of 8 feet, followed by stiff low plasticity clay till 11 feet, followed by sandy gravel layer till 14.5 feet, and 0.5 feet of weathered limestone to a maximum termination depth of 15 feet. 3. The subsurface soils at boring B-3, consists of 10" concrete pavement and base material, followed by a very stiff to hard clayey sand layer to a depth of 12 feet, followed by sandy gravel layer till 14.5 feet, and 0.5 feet of weathered limestone to maximum termination depth of 15 feet . 4 . The subsurface soils at boring B-4, consists of 8 feet of stiff clayey sand layer, followed by hard low plasticity clay till 11 feet, and stiff sandy lean clay till 15 feet, followed by 5 feet of medium dense clayey sand layer to a maximum termination depth of 20 feet. 5. Groundwater was encountered in all the borings except boring B-3 during or after completion of the drilling operations. Groundwater was encountered at a depth between 5 and 12 feet during and after completion of drilling of borings B-1, and B- 2 . At boring B-4 ground water was encountered at 19 feet during drilling, but it was not encountered after drilling operations . It should be noted that groundwater levels will fluctuate with seasonal changes in moisture conditions. 6. A laboratory testing program, consisting of moisture contents, Atterberg limits, minus 200 sieve analyses, and unconfined compressive strength tests, were performed on select soil samples. The testing results were summarized and included in Appendix A . 7. We recommend the junction box to be supported on a mat foundation at a depth of 12 feet. The mat foundation should be designed such that the applied net bearing pressure does not exceed the total allowable bearing pressure of 1,500 psf if the foundation is placed on natural soil at a depth of 12 feet. This bearing capacity value includes a factor of safety of two. 8. A minimum of 10-inch thick concrete pavement is recommended for a 30-year design life period. In addition, we recommend that eight inches of the subgrade soils be stabilized with 6% lime at locations where the subgrade soils are cohesive (clays) and with lime-flyash (2% lime, 8% flyash) at locations where the subgrade soils are . cohesionless (clayey sands). These percentages are provided for estimation purposes. The exact amount of lime or lime-flyash shall be determined for subgrade soils by conducting laboratory tests on the exposed subgrade material during construction. · Please note that the executive summary provided above does not fully detail our findings and opinions. Descriptions of the full extent of our findings and opinions are only presented through our full report. 11 2 INTRODUCTION 2.1 Project Description HVJ Associates, Inc. was retained by Freese and Nichole, Inc. to provide geotechnical investigations for Harley Avenue Street reconstruction From Rip Johnson Drive to University Drive in Fort Worth, Texas. A site vicinity map is presented on Plate 1. This project involves providing pavement design recommendations in accordance with City of Fort Worth, and design guidelines for the foundation of Junction Box. The purpose of the geotechnical investigation is to perform borings at the site, perform laboratory tests, and provide design guidelines for the proposed pavement and junction box. 2.2 Geotechnical Investigation Program The primary objectives of this study were to gather information on subsurface conditions at the site and to provide design recommendations for the proposed pavement and junction box. The objectives were accomplished by: 1. Drilling and sampling three 15-foot and one 20-foot borings, below the existing ground. These borings were used to determine soil stratigraphy and to obtain samples for laboratory testing; 2. Performing laboratory tests to determine physical and engineering characteristics of the soils; and 3. Performing engineering analyses to develop design guidelines and recommendations and presenting this information in a report. Subsequent sections of this report contain descriptions of the field exploration, laboratory-testing program, and the general subsurface conditions observed. Also presented in this report are descriptions of both the prescribed design recommendations and the construction considerations. 3 FIELD INVESTIGATION 3.1 Geotechnica) Borings The field exploration program undertaken at the project site was performed on March 10, 2010 . Subsurface conditions at the site were evaluated by drilling and sampling three 15-foot and one 20- foot borings, below the existing ground. A site plan showing the approximate boring locations is presented on the Plan of Borings, which is provided on Plate 3. 3.2 Sampling Methods Soil samples were obtained continuously to 10 feet and at five-foot intervals thereafter . Cohesive soil samples were obtained with a three-inch diameter, thin-walled (Shelby) tube sampler in general accordance with ASTM D -1587 . Each sample was removed from the sampler in the field and was carefully examined and classified according to the Unified Soils Classification System. The shear strengths of the cohesive soils were estimated in the field with a hand penetrometer. Suitable portions of each sample were sealed and packaged for transportation to our laboratory. Granular soils were sampled with the Standard Penetration Test (SPT) sampler in accordance with ASTM D1586 standard. Detailed descriptions of the soils encountered in the borings are given on the boring logs presented on Plates 4 through 7. A key to the soils classification and symbols used in the boring logs is also presented on Plate 8. 4 LABORATORY TESTING 4.1 Sample Examination and Classification Testing Soil samples transported to our laboratory were further examined and identified in accordance with ASTM D 2488 -Description and Identification of Soils. A preliminary soil classification was assigned to each soil sample based on ASTM D 2487 -Classification of Soil for Engineering Purposes. Classification testing was subsequently conducted on select samples, including measurement of moisture contents, Atterberg limits, and percentage of particles finer than No. 200 sieves . The result of each test was used to confirm or modify the given preliminary soil classification. 4 .2 Geotechnical Laboratory Testing Select soil samples were tested in the laboratory to determine applicable physical and engineering properties. All tests were performed according to the relevant ASTM Standards . These tests consisted of measurements of moisture content, Atterberg limits, percentage of particles passing the number 200 sieve, hand penetrometer reading, unconfined compression strength, dry unit weight, Sulfates, Chlorides, and pH. The Atterberg limits and percent passing the number 200 sieve were utilized to verify field classification of the soils according to the Unified Soils Classification System. The hand penetrometer and unconfined compression tests were performed to obtain approximations of the undrained shear strength of the soil. The type and number of tests performed for this investigation are summarized below: Type of Test Moisture Content (ASTM D2216) Atterberg Limits (ASTM D4318) Percent Passing No. 200 Sieve (ASTM Dl 140) Hand Penetrometer Sulfates, Chlorides, and pH Unconfined Compression (ASTM D2166) Dry Unit Weight (ASTM D2166) 2 Number of Tests 21 8 10 19 1 9 9 -' Laboratory test results are presented on the boring logs on Plates 4 through 7. A summary of the laboratory testing results is also included in Appendix A. Sulfate, Chloride, and pH test results are presented in Appendix B. 5 SITE CHARACTERIZATION 5.1 Site Location The project site is located in central part of Fort Worth, TX. Four borings are drilled at Harley A venue which are located to the north of IH 30 and west of IH 35W next to Trinity park. 5.2 General Geology According to the University of Texas at Austin, Bureau of Economic Geology "Geologic Atlas of Texas, Dallas Sheet," the project site area is located on Duck Creek Formation, map symbol (Kdc), limestone, aphanitic, in part bioclastic, locally burrowed, pyrite nodules up to 0 .2 foot, beds 0.2-2 feet thick, pinch and swell, medium gray to yellowish gray; weathers dark gray with yellowish-brown patches, locally forms topographic benches; marine megafossils and Gryphaea and ammonites; thickness 30-100 feet, thins southward. A geology map containing the project site is provided on Plate 2. 5.3 Soil Stratigraphy Our interpretation of soil, at the project site is based on information obtained at the boring locations. This information has been used as the basis for our conclusions and recommendations. Significant variations within areas not explored by the project borings will require reevaluation of our findings and conclusions. Boring B-1: The subsurface soils at boring B-1, consists of stiff to very stiff clayey sand with gravel till 4 feet, followed by very stiff high plasticity clay to a depth of 11 feet, followed by sandy gravel layer till 14.5 feet, and 0 .5 feet of weathered limestone to a maximum termination depth of 15 feet. Boring B-2: The subsurface soils at boring B-2, consists of stiff to very stiff high plasticity clay to a depth of 8 feet, followed by stiff low plasticity clay till 11 feet, followed by sandy gravel layer till 14.5 feet, and 0.5 feet of weathered limestone to a maximum termination depth of 15 feet . Baring B-3: The subsurface soils at boring B-3, consists of 10" concrete pavement and base material, followed by a very stiff to hard clayey sand layer to a depth of 12 feet, followed by sandy gravel layer till 14.5 feet, and 0.5 feet of weathered limestone to maximum termination depth of 15 feet. 3 Boring B-4: The subsurface soils at boring B-4, consists of 8 feet of stiff clayey sand layer, followed by hard low plasticity clay till 11 feet, and stiff sandy lean clay till 15 feet, followed by 5 feet of medium dense clayey sand layer to a maximum termination depth of 20 feet. Detailed descriptions of the · soil strata encountered in all of the borings are given in the boring logs presented on Plates 4 through 7. Keys to the terms and symbols used for soil classification on the boring logs are also included on Plate 8. 5.4 Groundwater Conditions Groundwater was encountered at a depth between 5 and 12 feet during and after completion of drilling of borings B-1, and B-2. For boring B-3 ground water was not encountered during or after completion of drilling, and for boring B-4 ground water was encountered at 19 feet during drilling and there was no trace of water after completion of drilling operations. However, it should be noted that groundwater levels will fluctuate with seasonal changes in moisture conditions. The water levels measured during and after drilling are reported on the boring logs presented on Plates 4 to 7. the following table summarizes the groundwater level readings during drilling and after completion of the drilling operations: Boring No. Water Depth During Water Depth After Drilling (ft) Drilling (ft) B-1 12 15 B-2 8 5 B-3 -- B-4 19 - 6 JUNCTION BOX RECOMMENDATIONS 6.1 General We understand that the project involves a junction box at an approximate depth of 12 feet below the existing ground surface. The junction box will be located near boring B-4. 6.2 Junction Box Foundation Recommendations We recommend the junction box to be supported on a mat foundation at a depth of 12 feet. The mat foundation should be designed such that the applied net bearing pressure does not exceed the total allowable bearing pressure of 1,500 psf if the foundation is placed on natural soil at a depth of 12 feet. This bearing capacity value includes a factor of safety of two (FS = 2). The applied net bearing pressure may be determined by: 4 1. Sununing the load applied to the foundation, the weight of the foundation, and the weight of any soil backfill placed directly above the foundation . 2 . Subtracting the weight of soil excavated from above the foundation depth. 3. Dividing the total by the base area of the foundation . The weight of soil may be taken as 130 pcf for soils above the water table and 65 pcf for soils below the water table. 6.3 Junction Box Excavation Pit Excavation Stability. Pit excavations shall be shored or some other equivalent means may be used to provide safety for workers and adjacent structures. Assessment of the need for excavation shoring or other measures required to provide a stable excavation, and the use of appropriate construction practices and/ or equipment is the contractor's responsibility. The lateral earth pressures recommended for short-term design are generally lower than the long- term pressures as the state of stress in the soil changes from "at rest" to "active" conditions immediately after excavation. In calculating the "design" lateral earth pressures, a combination of lateral soil pressures; hydrostatic water pressures; and surcharge loads need to be considered. We recommend that pressure distribution as shown on Plate 9 be used, and that the hydrostatic water pressure be computed by assuming the groundwater table to coincide with the ground surface. Calculation of these pressure components is explained on Plate 9. Pit Bottom Stability. Bottom instability results from inadequate shear strength in clay soils to resist stress relief at the base of the excavation, or from piping of water bearing granular soil. This mode of failure results in loss of ground at the ground surface outside the pit and heave of the excavation base inside the pit. Our calculations indicate that pit will have a factor of safety in excess of 2.0 against bottom heave . Our calculations assume no water is encountered during the excavation. Based on our boring log, water was encountered at a depth of 19 feet during drilling. If groundwater is encountered during construction, adequate dewatering of water bearing layers below the base of the pit should be performed to bring the water level in those layers to at least three feet below the base of the excavation. Loss of Ground. Installation of pits may experience some loss of ground around the outside of the excavation due to sloughing of material into the excavation . If proper construction procedures are followed, little or no loss of ground should occur. If loss of ground is excessive, it may cause damage to structures, pavement and services located near the excavation. If loss of ground does occur, soft disturbed soils may develop beneath existing pavement and utilities located close to the excavation location . Corrective measures to address loss of ground problems often include improved dewatering and/ or grouting around the pit from the ground surface or within the pit. Repairs associated with loss of ground often include making up for ground loss through placement of cement stabilized sand fill. 5 6.4 Select Fill and General Earthwork Recommendations Select fill required to raise the grade or backfill should consist of lean silty or sandy clay with a liquid limit less than 40 and a plasticity index between 7 and 20. Fill material that is used should be placed in loose lifts not exceeding eight inches and should be compacted to 95 percent of standard Proctor maximum dry density as determined by ASTM D698. 7 PAVEMENT DESIGN RECOMMENDATIONS 7.1 General We understand that the project will also involve the reconstruction of the pavement along the existing Harley Avenue from Rip Johnson Drive to University Drive. We understand that this street is classified major arterial. 7.2 Rigid Pavement Section The recommendations presented in this report for the pavement design were developed in accordance with the "AASHTO Guide for Design of Pavement Structures", 1993 Edition. The design procedure for determining concrete slab thickness for rigid pavement is based on an extension of the algorithms that were originally developed from the AASHTO Road Test. The categories required for the design of pavement includes: (a) design variables, (b) performance criteria, (c) pavement structural characteristics, (d) material properties for structural design, and (e) reinforcement variables. Parameters relative to these categories are discussed below. Traffic Load and Design Period. Based on City of Fort Worth Pavement Design Standards Manual 2005, and assuming the streets are classified as Major Arterial, we have estimated a traffic loading of 13,500,000 ESAL (18-Kip equivalent single axle load). This estimate is based on annual ESAL of 300,000, a growth rate of 2 .5 %, and a design life of 30 years in accordance with the City of Fort Worth Pavement Design Standards Manual. Reliability Level and Overall Standard Deviation. A reliability level (R) of 85 percent was selected for the pavement design performance. A mean value of the overall standard deviation (S 0 ) was selected to be 0.39 for rigid pavement. Serviceability . The serviceability of a pavement is defined as its ability to serve the type of traffic that uses the facility. The condition of the pavement after the performance period is characterized by a Terminal Serviceability Index (Pt), which is a function of the pavement structure. We recommend that a Terminal Serviceability Index of 2.5 be used for all pavements. Since the time at which a given pavement structure reaches its terminal serviceability depends on traffic volume and the original or initial serviceability (P 0 ), some consideration also must be given to the selection of P 0 . As obtained at the AASHTO Road Test, a P O value of 4.5 was selected. Drainage. The treatment for the expected level of drainage for a rigid pavement is through the use of a drainage coefficient, Cd. A Cd value of 1.0 wa s selected for good quali ty o f drainage . We have assumed that good quality drainage will be used on this project. 6 - Load Transfer. The load transfer coefficient, J, is a factor used in rigid pavement design to account for the ability of a concrete pavement structure to transfer load across discontinuities, such as joints . Based on the values developed by AASHTO, a mean value of the load transfer coefficient G) of 2.7 was selected for the design of jointed reinforced concrete pavement with tied curbs. Loss of Support. This factor, LS, was included in the design of rigid pavement to account for the potential loss of support arising from sub base erosion and/ or differential vertical soil movement. An LS value of 1.0 was selected according to the AASHTO suggestion for the condition of stabilized soils beneath the pavement. Effective Modulus of Subgrade Reaction. Based on an estimated California Bearing Ratio of 2.0 %, we have estimated a subgrade resilient modulus of 3,000 psi. Based on the loss of support factor (LS) described previously (LS=l.O), an effective modulus of subgrade reaction (k) was found to b~ 52 pci. Concrete Elastic Modulus and Modulus of Rupture. A mean value of 600 psi for S'c was selected for the design. A value of 3.42 x 106 psi was used for the modulus of elasticity of the concrete (Ee) using the correlation recommended by the American Concrete Institute. Ee= 57,000(fc) O.S Where, E e = elastic modulus of concrete in psi and, f c = compressive strength of concrete in psi; a value of 3600 psi is used here. 7 .3 Rigid Pavement Thickness and Load Capacity Based on the above parameters, a minimum of 10-inch thick concrete pavement is recommended for a 30-year design life period. In addition, we recommend that eight inches of the subgrade soils be stabilized with 6% lime at locations where the subgrade soils are cohesive (clays) and with lime- flyash (2% lime, 8% flyash) at locations where the subgrade soils are cohesionless (clayey sands). These percentages are provided for estimation purposes. The exact amount of lime or lime-flyash shall be determined for subgrade soils by conducting laboratory tests on the exposed subgrade material during construction. Reinforcing Steel Requirement" Longitudinal and transverse reinforcing steel is required to resist warping stresses in the pavement section and to hold pavement cracks that develop tightly closed . In addition, reinforcement is required at pavement joints in order to prevent deflections across the joint. Recommendations for reinforcement at pavement joints are described in the AASHTO Pavement Design Manual. The amount of longitudinal and transverse reinforcement required depends on the distance between pavement joints. Various bar sizes and spacing's can be used to satisfy these reinforcement requirements, and the overall cross-sectional area of steel (As) required per foot of slab width can be calculated as follows: A =FLW s 2f s 7 Where: As Required cross-sectional area of reinforcing steel per foot of width F Coefficient of resistance between slab and subgrade L Distance between free transverse joints or between free longitudinal edges, feet W Weight of pavement slab, psf fs Allowable working stress in the steel, psi Slab Length. This refers to the joint spacing or distance, L, between free transverse or longitudinal · joints. Steel Working Stress . The allowable working stress (fs) in steel reinforcement is a value equivalent to 75 percent of the steel yield strength. Friction Factor. This factor, F, represents the frictional resistance between the bottom of the slab and the top of the underlying sub base or sub grade layer. Based on City of Fort Worth Pavement Design Standards Manual 2005, Friction Factors between pavement slab and material beneath slab shall be in accordance with Part II -Table 2.8 of the AASHTO Design Guide, except the friction factor for natural subgrade shall be no less than 1.0. Based on the values recommended by AASHTO, a friction factor of 1.8 can be used for the condition of stabilized soils beneath the pavement. Steel Requirements. The design consultant should determine reinforcing schedule after the joint spacing (Lin the equation above) is determined . Based on City of Fort Worth Pavement Design Standards Manual 2005, all rigid pavements shall be jointed reinforced concrete pavements CTRCP) or continuously reinforced concrete pavements (CRCP). Only steel reinforcement will be allowed. No plain jointed concrete pavements CTCP) will be allowed. Continuously reinforced concrete pavements (CRCP) will be allowed only if approved in advance in writing by the Engineer. Reinforcement for JRCP shall be designed in accordance with Part II -Section 3.4 of the AASHTO Design Guide, except maximum spacing for number 3 reinforcing bars shall be 24 inches center to center, and for larger bars the maximum spacing shall be 36 inches center to center. Reinforcement for CRCP (if CRCP is allowed by the Engineer) shall be designed in accordance with Part II -Section 3.4 of the AASHTO Design Guide, except transverse reinforcement shall have a maximum spacing for number 3 reinforcing bars of 24 inches center to center, and for larger bars the maximum spacing shall be 36 inches center to center. 7.4 Preparation of Suhgrade The subgrade soils along the pavement alignment generally consist of both cohesive and cohesionless soils. We recommend that at least eight inches of the subgrade be stabilized. Stabilization of the subgrade should increase the modulus of subgrade reaction and provide 8 - subgrade stability for construction during inclement weather. In addition, subgrade stabilization should enhance long-term pavement performance by reducing the tendency of the soil to displace by pumping. We recommend the following procedures for subgrade preparation. 1. Clear the existing pavement section. 2. Strip the surface soil to suitable depths. In areas where soft, compressible or loose soils are encountered, additional stripping may be required. Stripping should extend a minimum of two feet beyond the edge of the proposed pavement where possible . 3. Surfaces exposed after stripping should be proof-rolled in accordance with TxDOT Standard Specification Item 216 or equivalent City of Fort Worth specification. · If rutting develops, tire pressures should be reduced. The purpose of the proof-rolling operation is to identify any underlying zones or pockets of soft soils and to remove such weak materials. 4. Before stabilizing the subgrade, scarify the upper eight inches of exposed surface as required, mix with lime where cohesive soils are encountered or lime-fl yas h where cohesionless soils are encountered, and compact it to 95 percent of standard proctor maximum dry density (ASTM D698). The amount of lime or lime-fl yas h shall be determined for subgrade soils by conducting laboratory tests on the exposed subgrade material during construction. 8 DESIGN REVIEW HVJ Associates, Inc. should review the design and construction plans and specifications prior to release to make certain that the geotechnical recommendations and design criteria presented herein have been properly interpreted. 9 LIMITATIONS This investigation was performed for the exclusive use of Freese and Nichols, Inc. for the proposed Harley Avenue Street reconstruction in Fort Worth, Texas.
