优化沥青混合料配合比设计研究

Study on Designing of Optimizing Charge Ratio of Asphalt Concrete Composition

本文介绍了沥青混合料配合比设计优化的过程,通过研究集料骨架的形成规律,以及骨架形成条件下细料的填充特性,探索密级配骨架密实状态下的评价方法,最终设计出一个施工可行、成本可控,基本路用性能兼顾的沥青混合料配合比。

This paper presents the optimizing process of the design of charge ratio of asphalt concrete composition. Through pursuing the regulation of forming the aggregate framework and filling characters of the aggregate in its condition, we explore an evaluation method in a state of dense framework and finally design the charge ratio of asphalt concrete composition which makes it possible to proceed the engineering , control the cost and possess all the basic usages of highway.
