ASTM Subcommittee D01.44 on Traffic Coatings has recently approved a new standard, D 7377 , Practice for Evaluating the Water Wash-Off Resistance of Traffic Paints, and is developing a proposed new standard, WK16700 , Practice for the Determination of Drying Rate of Waterborne Pavement Marking Paints Using a Test Chamber. The subcommittee is part of ASTM International Committee D01 on Paint and…, New Practice Measures Paint Resistance to Hard Rain, Hard rain sometimes falls soon after traffic paint has been applied to a road surface. Subcommittee D01.44 developed D 7377 to simulate hard rain conditions to determine the water wash-off resistance of an applied traffic paint film. D 7377 can be used to compare conventional and fast-dry traffic paints as well as the latex binders used in them for their relative ability to withstand heavy rain…, Proposed Standard to Measure Paint Drying Rate, Shay says that the subcommittee welcomes participation from all interested parties, particularly state Department of Transportation staff and liquid traffic paint makers, in all of its activities, including the development of WK16700 , a proposed standard that is designed to conveniently measure the drying rate of waterborne pavement marking paints under practical conditions of high humidity…

Two recently formed task groups on preparing pervious concrete specimens and research will be participating in the first meeting of the new Subcommittee C09.49 on Pervious Concrete from 8:00 to 10:00 a.m. on June 25 during the ASTM Committee Week in Norfolk, Va. C09.49 is part of ASTM International Committee C09 on Concrete and Concrete Aggregates. Heather Brown, Middle Tennessee State University…, Standardization News, , Karthik Obla, chair of Subcommittee C09.49, noted that there has been a resurgence in interest in pervious concrete due to the U.S. Environmental Protection Agency’s recent recognition of its use as a best management practice for storm water management. An increasing focus on sustainability and the green movement has also contributed to the importance of pervious concrete as a building material…
