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…

Soil and rock monitoring programs that use inclinometer probes often run for several years. Normal wear and tear can degrade the probe’s ability to produce useful surveys, though this degradation can happen incrementally and may go unnoticed for some time. A new standard developed by ASTM International Committee D18 on Soil and Rock, D 7299 , Practice for Verifying Performance of a Vertical…
