Combined with the engineering practice of Huai-tong expressway,volume performance, strength,stiffness index,coefficient of shrinkage,crack resistance index of the coarse aggregate less powder dense cement stabilized macadam were studied deeply.The result of the study shows:The skele-ton crack gradation cement stabilized macadam gradation compared with suspension type gradation is more compact,with better strength,shrinkage,crack resistance performance features.And reduce the crack, save the cost.At the same time,this paper also combines with the highway engineering practice,key construction technology of skeleton crack resistance of cement stabilized macadam base are studied.
