浅谈沥青混合料配合比优化设计

Elementary Discussion on Optimization Design of Mixing Ratio of Asphalt Mixture

该文结合实际工程,介绍了其沥青混合料配合比的优化设计。通过对邵永高速公路工程沥青路面中面层AC-20(C)改性沥青混合料配合比设计的试验,提出对沥青混合料材料的要求、矿料组成、确定用油量等问题的看法,以及对沥青混合料配合比设计的优化,从而达到既满足工程质量要求,又降低工程成本的目的。

The article introduces the optimization design of mixing ratio of asphalt mixture used in the practical projects.According to the test of the mixing ratio design of the surface AC-20(C) modified asphalt mixture in the asphalt pavement of Shaoyong Expressway Project,the article puts forward the material requirement of asphalt mixture,the composition of mineral materials,the determination of oil content,and the optimization design of mixing ratio of asphalt mixture so as not only to satisfy the engineering quality requirements,but also to reduce the engineering cost.
