[0002] Cement stabilized macadam base is the main load-bearing structure layer of semi-rigid asphalt pavement, which has the advantages of high overall strength, good plate body and durability, low cost, and convenient construction. However, if the construction quality control is poor, the phenomenon of partial aggregate segregation is prone to occur. Segregation reduces the overall strength and stability of the pavement base, which leads to early damage of the asphalt pavement and shortens the service life of the asphalt pavement. Therefore, how to effectively control the segregation of the mixture during the storage process in the silo has been a technical problem to be solved in the field of highway construction.
