摘 要: | 借鉴国外壳牌车辙预估方法,分析沥青稳定碎石基层沥青路面结构的抗车辙性能,并与半刚性基层沥青路面结构进行对比分析.结果表明:不论是沥青稳定碎石基层还是半刚性基层沥青路面结构形式,车辙主要发生在表面层和中面层;与半刚性基层沥青路面相比,沥青稳定碎石基层沥青路面结构产生的车辙深度增加不大.从提高沥青稳定碎石基层沥青路面的抗车辙性能角度出发,建议可着重提高沥青中上面层的抗车辙性能,并且ATB-25沥青稳定碎石基层厚度设置在15~20cm之间比较适宜.

Abstract: | Using methods for preapraisal of shell rut-resistance abroad,the paper analyses rut-resistance of asphalt pavement structure of asphalt-stabilized macadam base and makes the comparative analysis with asphalt pavement structure of semi-rigid base.Results indicate that the asphalt-stabilized macadam both and the semi-rigid base,their ruts mainly arise on surface layer and mid-surface year;by contrast to asphalt pavement of semi-rigid base,the rut depth which the asphalt pavement structure of asphalt-stabilize... |
