离析现象是沥青路面施工过程中经常出现的问题,严重的离析会导致沥青混合料的各种力学性能和使用性能的下降,严重影响路面的施工质量,并造成路面的破坏,缩短路面的寿命。本文通过对沥青混合料拌合、运输、摊铺和碾压过程的研究,分析了沥青混合料离析产生的原因,对其预防措施和评价方法进行了探讨,以期在工程实践中参考。 Segregation is a common problem in the asphalt pavement construction. Severe segregation can lead to various mechanical properties and serviceability of the asphalt mixture, seriously affecting the construction quality of pavement, causing pavement damage and shortening the life of the pavement. In this paper, the reasons for the segregation of asphalt mixture are analyzed through the research on the process of mixing, transportation, paving and rolling of asphalt mixture. The preventive measures and evaluation methods are also discussed, with a view to the reference in engineering practice.
