PDF In-Situ Stabilization of Road Base Using Cement - A Case

rehabilitation involved in-situ stabilization of the existing road base material using cement. The pavement works involved, milling of the existing bituminous layers to a depth of about 175mm, in-situ cement stabilization of the road base to a thickness of 200mm, and overlay with 230mm asphalt concrete. Field and laboratory tests were carried
