摘要
废旧沥青混合料作为公路基层材料具有很大的潜力,可以有效利用废旧沥青混合料,做到废物利用,减少环境污染。针对路面基层的技术要求,根据废旧沥青混合料的颗粒组成,进行了配合比设计和各项路用性能试验。试验结果表明,掺废旧沥青混合料的水泥稳定碎石基层具有良好的强度、耐久性和抗裂性等路用性能,完全可以替代细集料在公路基层中应用。
As a highway base material, waste asphalt mixture has great potential. The effective utilization of waste asphalt mixture not only utilizes waste, but also reduces the pollution of environment. In allusion to the technical requirement on pavement base, mix proportion design and road performance tests are carried on according to the grain composition of waste asphalt mixture. The test results show that the cement-stabilized macadam base with waste asphalt mixture additive has good performance on strength, durability, and crack resistance. It can be used in highway base instead of fine aggregate.
