| Abstract: | To counter the default of cracking easily of cement-stabilized macadam base course,the gradation design theory and orthogonal trail design method are used to select manifold representative aggregate gradation design schemes based on investigation fruits.Gradation design method and scheme of cement-stabilized macadam with well crack resistance performance are selected by mechanics and physics performance tests,and reasonable gradation composition of cement-stabilized macadam base course materials are discussed. |

| Keywords: | cement-stabilized macadam orthogonal trail gradation composition unconfined compression strength splittiting tensile strength dry shrinkage strain temperature shrinkage strain |
