An extensively revised standard and a proposed new standard are among the latest activities pursued by ASTM International Committee D18 on Soil and Rock. Subcommittee D18.11 on Deep Foundations has completed revisions to D 1143 , Test Method for Deep Foundations Under Static Axial Compressive Load, while Subcommittee D18.25 on Erosion and Sediment Control Technology is now working on proposed new…, ASTM D 1143, Test Method for Deep Foundations Under Static Axial Compressive Load, D 1143 covers procedures for testing vertical or inclined deep foundations individually or in groups to determine the axial deflection in response to a static axial compressive load. Subcommittee D18.11 has recently approved an extensive revision of D 1143 that reflects the latest technology used for these purposes. The following are the biggest changes to D 1143, according to Paul Bullock,…, WK13229, Test Method for Determination of Hydraulically Applied Fiber Matrix Performance in Protecting Hill Slopes from Rainfall-Induced Erosion, Subcommittee D18.25 is seeking participation in the ongoing development of WK13229 , particularly from testing laboratories and tackifier manufacturers/importers. WK13229 covers the guidelines, requirements and procedures for evaluating the ability of hydraulically applied fiber matrix to protect hill slopes from rainfall-induced erosion. For this protection to happen effectively, the fiber…
