AC-16C热拌沥青混合料目标配合比设计在山区市政道路改造中的应用

Application Example of Target Proportioning Design of AC-16C Type Hot-mixed Asphaltic Mixture for Municipal Road Reconstruction Project in Mountainous Area

针对英德市区的气候条件、集料质量,及交通状况,结合英德市区道路沥青改造工程的实践,从原材料及其级配的确定以及评价指标等方面,系统介绍了AC-16C沥青混合料目标配合比设计过程,通过中心试验室的验证以及施工过程的现场抽检,检验了该目标配合比设计的优越性,为促进山区道路沥青改造提供了有益的探索。

Based on the practice of road asphalt rebuilding engineering in Yingde City,this paper makes systematic introduction to the design process for target proportioning of AC-16C type asphalt mixture from three respects：raw material, gradation determination, evaluation index,considering climate condition at Yingde City. aggregate qualities and traffic status.Also the superiority of target proportioning design has been verified by the central laboratory and the on-the-spot ampling inspection. And the beneficial exploration can promote mountainous road asphalt rebuilding.
