关于沥青混合料温度离析现象的研究

Research on Temperature Segregation Phenomenon of Asphalt Mixture

为了保证沥青路面在有效的压实时间内完成高质量的碾压,很有必要对沥青混合料的温度离析现象进行研究.依托宿迁-新沂高速公路工程,对运料车上不同位置和深度沥青混合料的温度进行测量,结合摊铺路横断面上不同位置沥青混合料的温度分布情况,对沥青混合料的温度离析现象进行研究.通过对温度离析现象的研究,来指导现场的施工,提高工程的施工质量.

To guarantee high-quality compaction of asphalt pavement in effective compaction time,it is necessary to research the temperature segregation phenomenon of asphalt mixture. Based on the test results of Suqian-Xinyi highway,different location and depth temperature of asphalt mixture in the truck was measured.Combined with the temperature in different location of the road,the temperature segregation phenomenon of asphalt mixture was studied. The construction was guided through the study of temperature segregation,so that the quality of construction project was improved.
