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

The ability to provide the correct amount of protection is one of the important elements in the development of protective clothing worn by individuals who apply pesticides as part of their jobs. While overprotection in hot climatic conditions can result in heat stress and low compliance, some of the existing design-based requirements can result in too little protection, as material performance…, CONTACT:, ASTM Committee F23 Next Meeting:, Jan. 26-28, 2010, January committee week, San Antonio, Texas, Technical Contact:, Anugrah Shaw, University of Maryland Eastern Shore, Princess Anne, Md., Phone: 410-651-6064; ashaw@umes.edu, ASTM Staff Contact:, Stephen Mawn, ASTM International, Phone: 610-832-9726; smawn@astm.org, ASTM PR Contact:, Barbara Schindler, ASTM International, Phone: 610-832-9603; bschindl@astm.org Release #84 54/Jan2010
