用最大粘结力法确定沥青稳定基层的最佳沥青用量

Research on Mix Design of Asphalt Stabilized Base by Using Maximum Cohesive Force Method (MCFM)

采用最大粘结力法设计沥青稳定基层的配合比,并与传统的马歇尔方法进行对比。最大粘结力法这一方法的出发点是寻求最佳的沥青用量以使得混合料的粘结力达到最高,从而使得沥青稳定基层具有最好的抗变形和抗疲劳的能力。研究结果表明,和传统的马歇尔方法比较,以最大粘结力为目标设计的沥青稳定基层性能良好,是一种试验方法简单而且有效的方法。

<Abstrcat>In this paper the maximum cohesive force method (MCFM) is adopted to carry out the component design of asphalt stabilized base and compared with conventional Marshall method.The key point of MCFM is to look for the best Asphalt ussge for the maximum cohesive force of the mixtures,so that asphalt stabilized base can have a best anti-deformation and anti-fatigue capability.The result shows that comparing with the conventional Marshall method,the asphalt mixture made with MCFM has good performance,and that MCFM is also a simple and effective test method.
