| 摘 要： | 研究了水泥稳定旧沥青混凝土路面材料的再生机理,通过强度对比试验和微观结构分析,探讨了沥青和半刚性基层材料对水泥稳定再生材料强度的影响;试验证明随着沥青混合料比例的增大,材料的强度降低;旧集料与水泥水化产物间存在薄弱界面,对强度有不利影响.

| Abstract: | The recycling mechanism of cement stabilized recycled asphalt concrete pavement material is studies.By means of the experiment of strength and analysis of microstructure,the influence of the asphalt and semi-rigid base material on the strength of cement stabilized recycling materialis is discussed;the experiments prove that the strength decreases with the asphalt mixture ratio increases;there is a weak interface between the old aggregate and hydration products of cement which have an adverse effect on the s... |
