沥青混合料配合比设计及路用性能研究

The road using function research and pitch mixs match ratio design

结合某旧水泥混凝土路面沥青罩面改造方案,根据各结构层的受力特点和功能要求,通过试验研究了不同类型级配的沥青混合料路用性能,从而优选出技术可行、经济合理的各结构层最佳材料组成方案。

The paper joins together the some old cement concrete road pitch cover reforms project, based on stress characteristic and different function request, studys vary type graduation pitch road using function with experiment to optimization out technique and economic the best material layer reasonable constitute project.
