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…
