沥青混合料稳定性设计试验方法探讨

Approach to Design and Experimental Methods of Asphalt Mixture Stability

对比分析了采用击实成型试件的Marshall法与采用旋转压实成型的GTM法和SGC法对这一类型沥青混合料组成设计的影响,探讨了提高混合料高温稳定性的设计和试验方法。研究发现,采用SGC旋转压实法设计不便保证了其他路用性能,还提高了沥青混合料的高温稳定性。

The paper by comtrast analyzes influence of adopting Marshall methods of sample forming by compaction along with GTM amd SGC methods of sample forming by rotary compaction on constituent design of asphalt mixture of present category. It makes an approach to the design to strengthen stability of mixture at high - temp and the experimental methods. Studied results have found that adopting SGC method ensures not only other road usage performance but aloso enhances stability of asphalt mixture at high - temp.
