4.1 The extent of cracking or pitting of bituminous films is a measure of the extent of deterioration due to weathering. Failure due to cracking is more accurately determined electrically than visually.4.2 Failure determined by this test method will depend not only on the characteristics of the bituminous material and the extent of weathering, but also on the film thickness, and the amount and type of mineral filler present.4.3 Tests on a similar material of known weathering characteristics (a control) exposed at the same time as the test material is strongly recommended as a check on the validity of the test results.1.1 This test method covers the use of a spark-generating apparatus for determination of failure due to cracking of bituminous materials undergoing accelerated or outdoor weathering on electrically conductive backings.1.2 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.1.3 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.1.4 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 The use of PBGM as barrier materials to restrict liquid migration from one location to another in soils has created a need for a standard test method to evaluate the quality of PBGM seams. In the case of PBGMs, it has become evident that seams can exhibit separation in the field under certain conditions. Although this is an index-type test method used for quality assurance and quality control purposes, it is also intended to provide the quality assurance engineer with sufficient seam shear data to evaluate seam quality. Recording and reporting data will allow the quality assurance engineer to take measures necessary to ensure the repair of seams with unacceptable strength during facility construction, and therefore, minimize the potential for seam separation in service.1.1 This test method presents the procedures used for determining the quality of prefabricated bituminous geomembrane (PBGM) bonded seams subjected to a shear test. It describes a destructive quality control test used to determine the integrity of PBGM seams.1.2 This test procedure is intended for PBGMs only.1.3 The type of thermal field seaming technique used to construct PBGM seams include the following.1.3.1 Torch-On—This technique melts two PBGM surfaces to be seamed by running a flame from a propane torch between them. Pressure is applied on the top or bottom, or both PBGMs, forcing together both surfaces to form a continuous bond.1.3.2 Hot Air—This technique introduces high-temperature air or gas between two PBGM surfaces to facilitate melting. Pressure is applied on the top or bottom, or both PBGMs, forcing together both surfaces to form a continuous bond.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.

1.1 This provisional test method covers the determination of maximum specific gravity of and density of uncompacted bituminous paving mixtures at 25°C (77°F).1.2 The values stated in SI units are to be regarded as the standard. The other units given may be approximate and are given to help the user interpret units on available standard equipment used with this provisional test method.1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.Note 1—Provisional standards require only subcommittee consensus and are published for a limited time of two years. The provisional process was used because agencies and private organizations have an immediate need for a method that will save time and accurately reduce water absorption by absorptive mixes, eliminating the need for post vacuum "dry back" correction and stripping. This method provides a quick way to test loose bitminous mixtures for maximum specific gravity.
