摘要
简要介绍了Superpave混合料的设计思想 ,强调了如何准确测量沥青混合料压实试件毛体积密度的重要性 ,分析了表干法在测量Superpave混合料试件方面的局限性 ,同时通过试验说明了表干法与Corelok法在测试结果方面存在显著的差异 。
This paper briefly introduces the design concept of Superpave mixture, emphasizes the importance of correctly measuring the bulk gravity of asphalt mixture compacted samples, and analyzes the limitation of the surface-dry condition method used for measuring the bulk gravity of Superpave mixture samples. The experimental results show that there is a big difference between the surface-dry condition method and the Corelok method, so we suggest to develop a similar domestic equipment to satisfy the needs of rapid development of highway construction in China.
