Two new ASTM International standards will aid in the recent national movement to develop a mechanistic-empirical design guide for pavements. The new standards, developed by ASTM International Committee D35 on Geosynthetics, will each cover quantification of fundamental material properties for pavement components. The standards, ASTM D7499 , Test Method for Measuring Geosynthetic-Soil Resilient…, ASTM Committee D35 Next Meeting:, Feb 2-4, 2011, January Committee Week, Baltimore, Md., Technical Contact:, Eli Cuelho, Western Transportation Institute, Montana State University, Bozeman, Mont.; Phone: 406-994-7886; elic@coe.montana.edu, ASTM Staff Contact:, Christine Basile, Phone: 610-832-9728, cbasile@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8605

Since the appearance of the first California-type models around 1940, the profilograph has been a popular device used for quality control in the construction of pavements. Both roadway and airfield landing agencies have adopted roughness indexes computed from profilograph-derived measurements as a level of construction quality. Emerging high-speed inertial profilers can now quickly collect…

A proposed new standard being developed by ASTM International Committee E17 on Vehicle-Pavement Systems will be the first to describe how truth-in-data should be applied to traffic monitoring data collection, summarization and reporting. WK25280 , Practice for Highway Traffic Monitoring Truth-in-Data, is under the jurisdiction of Subcommittee E17.52 on Traffic Monitoring. Current traffic…

Being able to compile and interpret data on how traffic turns through an intersection could have an impact on future environmental and safety decisions regarding intersection geometry and traffic control. However, until recently no standard has existed to properly obtain and use this data. Now, ASTM International Committee E17 on Vehicle-Pavement Systems has approved E2667 , Practice for…

A new ASTM standard developed by ASTM International Committee D35 on Geosynthetics fills a need for an internationally recognized standard to ensure that EPDM sheet material received by customers is consistent regardless of the manufacturer. The new standard, D7465 , Specification for Ethylene Propylene Diene Terpolymer (EPDM) Sheet Used in Geomembrane Applications, is under the jurisdiction of…

ASTM International Committee D35 on Geosynthetics invites all interested parties to participate in the development of a proposed new standard, WK15082 , Specification for Measuring the Asperity Height of Textured Geomembrane. The proposed standard is being developed by Subcommittee D35.10 on Geomembranes. Although asperity height is specified throughout the geosynthetic industry, a procedure to…

Drawing on the best practices of the U.S. Federal Highway Administration and the states, ASTM International Committee E17 on Vehicle-Pavement Systems has developed a new standard, E 2561 , Practice for Installation of Inductive Loop Detectors. E 2561 is under the jurisdiction of Subcommittee E17.52 on Traffic Monitoring. Inductive loop detectors are installed in sawed slots in roadway pavement…

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…

ASTM International Committee F41 on Unmanned Undersea Vehicle Systems invites all interested parties to participate in a new task group, F41.90.01 on Unmanned Surface Vehicles. With the addition of this new task group, the name of Committee F41 will be changed to Unmanned Maritime Systems. Task Group F41.90.01 is seeking new members with expertise in unmanned surface vehicles to complement the…
