5.1 This guide outlines general installation procedures and precautions for the application of sodium bentonite needle-punched geotextile waterproofing systems.5.2 This guide is not all inclusive and is intended only to supplement detailed drawings and specifications from designers and the installation guidelines of manufacturers. Manufacturers of some of the systems addressed by this guide require proprietary products and special procedures not described in this guide. Manufacturers’ guidelines and details applicable for each site construction condition encountered on a project should therefore be considered in the application of this guide.1.1 This guide covers general installation guidelines of waterproofing membranes produced as a composite of sodium bentonite contained within two interlocked needle-punched geotextiles for designers to consider when developing project-specific drawings and specifications. This guide covers construction applications where the waterproofing is applied to the positive side of below-grade cast-in-place concrete foundation walls, both backfilled and support of excavation (SOE) construction, and under concrete pressure slabs. This guide does not cover plaza deck construction applications, either split-slab construction or pavers on pedestals, or vegetated green roof waterproofing applications.1.2 This guide does not cover sodium bentonite waterproofing membranes produced with a corrugation paper carrier, bentonite bonded to a geomembrane, and spray-applied bentonite systems.1.3 For the purpose of this guide, concrete is assumed to be cast-in-place with a surface profile as recommended in Guide D5295/D5295M, consolidated in accordance with applicable guidelines in ACI 309, structurally sound, able to accept the weight of anticipated loads, and meets the local building code requirements. All components of the waterproofing system are assumed to comply with any federal, state, and local environmental regulations that may be in effect at the time of installation. Expansion joints, insulation, and drainage layers are beyond the scope of this guide.1.4 This guide does not cover sodium bentonite geotextile membranes installed on below-grade foundation walls and slabs constructed with masonry materials, precast concrete, or pneumatically applied concrete (that is, shotcrete).1.5 The values stated in SI units are to be regarded as standard. The unit values given in parentheses are for reference information only.1.6 Different sodium bentonite geotextile membranes have different materials of composition and construction which can affect physical properties. The procedures contained in this guide, therefore, may not be universally applicable to all sodium bentonite geotextile membranes under all field conditions.1.7 This guide does not purport to assign responsibilities of quality assurance or quality control. Specific quality assurance and quality control items should be addressed in project specifications and contract documents.1.8 This guide does not purport to include requirements for warranties associated with the waterproofing materials or installation.1.9 This guide does not purport to include all detailing techniques to address various conditions that can be encountered on construction projects.1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method is used to determine the density of construction slurries in the laboratory and field. For freshly mixed slurry, this test method may be used as an indicator of mix proportions. For in-trench slurry or in-borehole slurry, a certain value may be specified for maintaining trench or borehole stability.NOTE 1: The quality of the result produced by this standard depends on the competence of the personnel performing it and the suitability of the equipment and facilities being used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself ensure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.1.1 This test method covers the determination of the density of slurries used in slurry construction techniques, such as those used to drill borings, maintain trench stability, perform ground improvement, and form hydraulic barriers. This test method is modified from API Recommended Practice 13B.1.2 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only and are not considered standard. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard.1.2.1 Note that unitless specific gravity is equivalent to SI density in g/cm3.1.2.2 It is common practice in the engineering/construction profession to concurrently use pounds to represent both a unit of mass (lbm) and of force (lbf). This practice implicitly combines two separate systems of units; the absolute and the gravitational systems. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. As stated, this standard includes the gravitational system of inch-pound units and does not use/present the slug unit of mass. However, the use of balances and scales recording pounds of mass (lbm) or recording density in lbm/ft3 shall not be regarded as nonconformance with this standard.1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this test method.1.3.1 For purposes of comparing a measured or calculated value(s) with specified limits, the measured or calculated value(s) shall be rounded to the nearest decimal of significant digits in the specified limit.1.3.2 The procedures used to specify how data are collected/recorded or calculated in the standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This practice provides basic criteria for the development and operation of a certification body, the development and operation of a certification program, and the development and use of customary mechanisms to evaluate a candidate’s knowledge, skill, and ability.4.2 The basic criteria provided by this practice are intended to be supplemented by more specific criteria serving the requirements of the certification body.4.3 The certification body and its program, accredited according to the requirements of ANSI/ISO/IEC 17024 and this practice, shall be considered as having met the full intent of this practice.1.1 This practice provides supplemental requirements to those of ANSI/ISO/IEC 17024 for bodies that certify personnel engaged in inspection and testing of construction activities and materials used in construction, including Special Inspection. ANSI/ISO/IEC 17024 provides generic requirements that can be adapted to any discipline where assurance that certified individual meets the requirements of the certification scheme. Therefore, certification bodies certifying personnel engaged in inspection and testing of construction activities and materials used in construction, including Special Inspection, must meet the requirements of this practice and ANSI/ISO/IEC 17024.1.2 This practice may be used as a reference by:1.2.1 Developers of standards requiring personnel certification in inspection and testing of construction activities and materials used in construction, including Special Inspection, as a reference to harmonize terminology and reduce confusion among users;1.2.2 Personnel certification bodies that establish criteria and certify construction inspection, construction testing, and Special Inspection agency personnel against specific requirements,1.2.3 Accreditation bodies that accredit certification bodies, and1.2.4 Users and specifiers as a reference when requiring personnel certification.1.3 This practice follows the format of ANSI/ISO/IEC 17024 and provides additional requirements where needed.1.4 Certification may be specific to a single test or inspection method or practice or a grouping or collection of methods or practices (any such method, code, or practice being hereinafter referred to as “method,” or collectively as “methods”).1.5 Personnel certification is an important aspect of the quality system of agencies engaged in inspection and testing of construction activities and materials used in construction, including Special Inspection. Certification of personnel is required to meet the personnel qualifications of Practice E329.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method is used to determine the percentage of sand by volume in construction slurry. The significance of this test method mainly relates to construction slurries used for concrete wall and drilled piers construction. The range of measurement is too limited for use in applications where the sand content is intended to be greater than 20 %, such as in the cases of cement bentonite or soil bentonite walls.5.2 A high sand content in the construction slurry is abrasive for construction plant such as pumps, and is furthermore adverse to the formation of a filter cake in applications where bentonite fluid is used to stabilize an excavation.NOTE 1: The quality of the result produced by this standard depends on the competence of the personnel performing it and the suitability of the equipment and facilities being used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself ensure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.1.1 This test method covers the determination of the sand content of bentonitic slurries used in slurry construction techniques. This test method has been modified from API Recommended Practice 13B.1.2 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Except, the sieve designation is identified using the “alternative” system in accordance with Practice E11 instead of the “standard system,” such that the sieve used is referred to as a No. 200 sieve, instead of a 75 µm sieve.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.1 The procedure described in this practice is used to design and construct an asphalt-rubber cape seal that will provide a wearing course when subjected to low to medium traffic volumes and where the pavement distress is due to block-type cracking resulting from pavement aging or reflective cracking only (not where there are clear indications of fatigue cracking due to repeated heavy axle loads).NOTE 2: Block cracking is defined in Practice D6433. See Appendix X1 for an example of block cracking due to aging.1.1 This practice covers asphalt-rubber cape seal, which is defined as the application of an asphalt-rubber seal coat placed onto an existing pavement surface, followed by the application of a conventional Type II or III slurry seal.NOTE 1: An asphalt-rubber seal coat is also known as a stress absorbing membrane (SAM), which consists of an asphalt-rubber membrane seal followed by the application of pre-coated aggregate chips.1.2 An asphalt-rubber cape seal is commonly used to extend the service life of low to medium trafficked and moderately distressed asphalt-surfaced pavements. The existing pavement condition can be used to determine the application rates for the asphalt-rubber binder and aggregate as well as the aggregate gradation. Pavements in relatively poor condition will require a coarser aggregate with a higher binder application rate.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This guide may be used as a reference of acceptable open-cut construction practices for the proper installation of buried fiberglass and thermoplastic pipe. This guide may be used as follows:4.1.1 Installation contractors have an awareness of the level of workmanship required and use this information for bidding purposes and during construction.4.1.2 Construction inspectors have a reference of acceptable installation practices.4.1.3 Specification writers may use this guide as a reference in contract documents.4.1.4 Designers may review this information during planning and design for factors to consider in the preparation of plans and specifications.4.1.5 The owner of the pipeline may use this guide as a reference for restoration of proper pipe support and embedment when original construction is disturbed due to repairs, modifications, or construction of adjacent or crossing pipelines or cables.4.2 This guide should not be used to replace project specification requirements, manufacturer's recommendations, plumbing codes, building codes, or ASTM installation standards, but may be used to supplement that information.1.1 This guide describes installation techniques and considerations for open-cut construction of buried pipe. Although this guide was developed for plastic pipe, the concepts of providing the appropriate soil support, care in handling, correct joining techniques, proper soil compaction methods, and prevention of installation damage may apply to any pipe.1.1.1 Plastic pipe refers to thermoplastic and fiberglass pipe.1.1.2 Thermoplastic pipe refers to pipe fabricated from polyvinyl chloride (PVC), polyethylene (PE), acrylonitrile-butadiene styrene (ABS), cross-linked polyethylene (PEX), chlorinated polyvinyl chloride (CPVC), or polypropylene (PP). A list of specifications for these products is given in Appendix X2.1.1.3 Fiberglass pipe refers to a glass-fiber-reinforced thermosetting-resin pipe. A list of ASTM specifications for these products is given in Appendix X2.NOTE 1: Appendix X2 cannot be considered inclusive because there may be unlisted, recently adopted ASTM specifications for new products that may be installed using this guide.NOTE 2: Only a few of the ASTM specifications listed in Appendix X2 include the associated fittings. While this guide applies to the installation of pipe, couplings, and fittings, no attempt was made to list all the possible fitting specifications that may be used in conjunction with the pipe specifications. Consult each specification or manufacturer for appropriate fitting standards.1.1.4 For simplification, the term pipe will be used in this document to mean pipe sections, fittings, and couplings.1.2 This guide contains general construction information applicable for plastic pipe and supplements the installation standards for the various types of pipe as described in Practices D2321, D2774, D3839, F690, and Guide F645.NOTE 3: This guide is not applicable for gas pipe applications as additional requirements may apply.1.3 Flexible pipe, such as thermoplastic and fiberglass, are typically designed to rely on the stiffness of the soil surrounding the pipe for support. The contract documents should describe the requirements of an appropriate soil support system. The construction practices described in this guide can be instrumental in attaining the required soil stiffness.1.3.1 A discussion of the interaction between a buried pipe and the surrounding soil and the importance of attaining proper soil support is in Appendix X1.1.3.2 Following these guidelines will be helpful in preventing local deformations in the pipe.1.4 This guide does not cover underwater installation, pipe that needs to be supported on piling, perforated pipe used for drainage, or gas pipelines.1.5 Pipelines through areas described as “expansive soils,” “collapsing soils,” landfills or water-logged land (such as swamps) should be constructed using site-specific installation procedures and are not discussed in this guide.1.6 This guide is not intended to cover all situations. Specific pipe characteristics, fluid transported, local site conditions, environmental concerns, or manufacturer's recommendations may require different guidelines.1.7 The construction practices presented in this guide may be affected by the installation requirements of owners, specifying organizations, or regulatory agencies for pipelines crossing roads and highways, other pipelines or cables, or waterways such as streams, drainage channels, or floodways.1.8 Culverts or pipe that are used as passages through water retaining embankments (for example, earth dams) may be constructed using the principles of this guide, if appropriate provisions are made to prevent water movement along the outside of the pipe (using impervious soils, cutoff collars, head walls, etc.).1.9 The values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are given for information only.NOTE 4: There is no similar or equivalent ISO standard covering the primary subject matter of this guide.1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
