摘要
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,影响路面的施工质量,并造成路面的破坏,缩短路面的寿命。文章对沥青混凝土路面施工中的级配离析、温度离析现象的原因进行分析和讨论,并提出了相应的改进工艺措施和防治技术。
Segregation phenomenon is often appeared in the process of asphalt pavement construction, serious segregation can lead to all kinds of mechanical properties of asphalt mixture and the use of performance degradation, affect the quality of road construction, and caused the destruction of the pavement, shorten the service life of pavement. In this paper, the reasons for the gradation segregation, temperature segregation phenomenon is analyzed and discussed, and it put forward the corresponding improvement craft measures and prevention and control technology.
