New standard will support measuring quality of cement in geosynthetic composite mats

June 29th, 2020

A new ASTM International standard will aid engineers and specifiers looking to understand the quality and strength of cement contained in geosynthetic cementitious composite mats (GCCMs). ASTM’s geosynthetics committee developed the new standard, which is needed to allow for a consistent industry method for the application of compression strength in GCCMs. GCCMs are flexible, concrete-impregnated […]

A guide for specifying drainage geocomposites

April 1st, 2020

By Lisa L. Damiano and Eric S. Steinhauser In September 2017, ASTM International released its Standard Guide for Specifying Drainage Geocomposites (ASTM D7931). The standard provides a guideline for calculating engineering properties related to drainage geocomposites, specifically allowable flow rate, associated reduction factors and shear strength properties. In basic terms, it codified design procedures so […]

Proposed ASTM geocells standard aims to support soil stability in road projects

January 23rd, 2020

A proposed ASTM International standard will provide guidance for using geocells—open-celled geosynthetics that help hold soils and rocks in place—in roadway projects. Geocells are commonly used in road construction, earth retention and other construction projects. According to ASTM International member Eli Cuelho, there is currently no standard for using geocells in geotechnical and roadway projects. […]

Oh no! The GCL got wet! Now what?

February 1st, 2017

Authors’ note: The conditions This project started in central California in July 2014, and we watched the weather forecasts on the nightly news and we were calm. A few weeks later, the project is running longer than expected, and now we are watching the Weather Channel and reading Weather Underground and Accuweather with more interest […]
