Cement stabilized macadam base has the advantages of high strength, low cost, wide source of raw materials , but it is unknowable that whether the cement stabilized crushed stone materials which are produced from Guangdong province can meet local road performance and specification requirements or not. This article is mainly to solve the problem that the study of the local materials of cement stabilized macadam base design specifications which is produced from Guangdong Province. Firstly，we select two suitable gradation to determine the amount of cement and optimum moisture content; Then, validating whether its seven days unconfined compressive strength, splitting strength and compressive resilient modulus are in compliance with the specification and in a suitable range or not. Thirdly，we explore the relationship between the various indicators and provide the note in construction.
