Measuring the reflectance of vitrinite dispersed in sedimentary rocks is one of the most commonly used tools for determining thermal maturity in hydrocarbon exploration, basin modeling and other geological applications. Despite this, there currently is not a consensus standard for making these measurements. ASTM International Committee D05 on Coal and Coke is developing a proposed standard to…

Three subcommittees of ASTM International Committee D35 on Geosynthetics are currently developing several proposed new standards. The topics covered in the following proposed standards are geosynthetic clay liners, geomembranes, and the development of a mechanistic-empirical design guide for pavements. Committee D35 will meet Jan. 30-Feb. 1, 2008, at the January Committee Week in Tampa, Fla.…, Subcommittee D35.04 on Geosynthetic Clay Liners, Responding to shrinkage issues involving geosynthetic clay liners, Subcommittee D35.04 has launched work on a proposed new standard, WK12239 , Test Method for Linear Dimensional Changes of Restrained Geosynthetic Clay Liners Under Cyclic Temperature and Hydration Conditions. WK12239 is an index test that covers the measurement of changes in linear dimensions of a geosynthetic clay liner that…, Subcommittee D35.10 on Geomembranes, Subcommittee D35.10 is currently developing two proposed new standards, WK14305 , Specification for Non-Reinforced PVC (Polyvinyl Chloride) Geomembrane Seams, and WK14311 , Guide for the Installation of Non-Reinforced Polyvinyl Chloride (PVC) Geomembranes. According to Mark Wolschon, engineers, specification writers, users, suppliers, manufacturers, fabricators and installers of PVC…, Subcommittee D35.01 on Mechanical Properties, There is currently a national movement to develop a mechanistic-empirical design guide for pavements. This initiative requires that the fundamental material properties for all components of the design be quantified. Subcommittee D35.01 is working toward this goal with the development of two proposed new standards, WK14361 , Test Method for Determining Small-Strain Tensile Properties of Geogrids…
