Abstract: At present, cement and two-ash stabilized semi-rigid base materials are prone to cracks, looseness and other diseases. In order to solve the cracks and durability problems, improve the quality of road driving. This paper proposes the construction technology of anti-cracking cement stabilized crushed stone base course. Based on specific engineering cases, this paper analyzes and discusses the key points of cement stabilized macadam base construction technology, in order to provide a reference for similar pavement construction.
