ASTM releases new geosynthetic cementitious composite mat standard
March 27th, 2018
The American Society for Testing and Materials (ASTM) released a standard March 26, 2018, for geosynthetic cementitious composite mats (GCCM), a new family of materials that can help control erosion, protect slopes and berms, and line ditches and culverts. The new standard (D8173) identifies proper layout, installation and hydration procedures for GCCM. It also describes […]
Editorial: The management of coal combustion residuals (CCR)
August 1st, 2017
The management of coal combustion residuals (CCR or “coal ash”) is a growth category for the geosynthetics industry. Multiple opportunities now exist using various types of geosynthetics due to the evolving federal and state regulations for handling CCR. In fact, geosynthetics have played a role in the regulations that have developed. “These regulations have been […]
Using geosynthetics for macroencapsulation for CCR on-site clean closure
August 1st, 2017
Coal combustion residuals (CCR) have been used for many years in the construction of berms and engineered structural fill applications, including embankments for highways, dikes, and levees. However, large, unencapsulated structural fill projects have become a focus of environmental concerns due to potential leaching of metals and structural failures. Cap-in-place of CCR surface impoundments is […]
