摘要
泡沫沥青再生混合料近年来在国省干线公路得到了很好的应用,其既可有效缓解反射裂缝的发展,又可与上下结构层形成很好的连接,起到有效的应力分散作用,而且在工期缩短与经济效益方面也有突出优势。本文以喀左建三线维修工程为依托,研究了泡沫沥青冷再生混合料在干线公路的设计、施工方法,并对设计过程中的材料选择、混合料性能进行了分析,对其在其他维修工程中的应用有指导作用。
The foamed asphalt recycled mixture has been well applied into the provincial trunk highways in recent years, which effectively alleviates the development of reflection crack, connects structural layers nicely, plays an effective role in stress dispersion, and shows prominent advantages in shorter construction duration and good economic benefits. In this article, based on maintenance works of the Kazuo-Jiansan highway, the design and construction method of the foamed asphalt cold recycled mixture of truck high-ways is studied, and the material selection and mixture performance during the design process is analyzed, which shall play a guiding role for the application of the technology in other maintenance works.
