The standard will cover the sampling, preparation and testing of coarse lightweight aggregate for pH and resistivity testing in the lab.
The test method is needed to address the properties of coarse lightweight aggregate for use in MSE wall applications. Currently there is no standard that adequately tests these materials for these properties. Several DOTS have developed special provisions that address the testing of these materials for the these properties and private owners have used these special provisions due to the lack of an appropriate ASTM standard. The users of the new standard would be government agencies,commercial testing labs and private designers.
