保护环境、节约资源和降低排放是当前交通基础设施建设中的重大技术问题,也是实现“四个交通”中“绿色交通”的重要体现。本文针对酸性片麻岩石料进行研究,通过合理的原材料的选择、级配设计优化以及最佳油石比条件下的沥青混合料性能验证,充分的论证该类型石料在高速公路面层中应用的可行性,并提出了在高等级道路中应用时的相关建议。
Protecting the environment, saving resources and reducing emissions are major technical problems in the construction of transport infrastructure and an important manifestation of the realization of “four transportation” and “green transportation”. In this paper, the study on the acidic gneiss rock, through the reasonable selection of raw materials, gradation design optimization and the best performance of asphalt mixture under the condition of asphalt to verify the feasibility of this type of stone in the highway surface layer feasible And put forward some suggestions when applying it in high-grade roads.
