Performance Specification for Geogrid Reinforced Aggregate Base

A performance specification has been developed for geogrid reinforced aggregate base, which utilizes the dynamic cone penetrometer (DCP) and light weight deflectometer (LWD) to test the aggregate base reinforced with geogrid. These quality assurance devices, in particular the DCP, are very familiar to construction inspection staff in Minnesota, and therefore this performance specification is expected to be readily implemented. In summary, the construction quality assurance test locations are selected to accurately represent the constructed aggregate base layer and the DCP or LWD is placed at the appropriately prepared test location. For both the DCP and LWD, the weight is raised and released to deliver a predetermined number of drops that result in a measured penetration (DCP-MV) or plate displacement (LWD-MV), which is then compared to a predetermined target value (DCP-TV or LWD-TV).
