ASTM Updates September 2009
This post contains a summary of geotechnical, materials testing, geosynthetic and related testing standards that were updated by ASTM during the month of September. This month there were not as many updates as the last couple, but a few that caught my eye are a new standard for measuring geosynthetic-soil resilient interface shear stiffness, a revision to the standard practice for laboratories testing concrete and concrete aggregates for use in construction and criteria for laboratory evaluation and a revision to the standard for measuring slump flow of self-consolidating concrete.
