温拌改性沥青在隧道路面工程中的应用技术研究

Study on application of warm mix modified asphalt in tunnel pavement engineering

在隧道摊铺沥青路面时,因其环境密闭性,沥青混合料的烟尘及热量得不到及时排出,有害气体会长时间笼罩施工区域。温拌改性沥青技术是主要以降低混合料生产、施工温度为目的,在密闭环境中的一种路面施工控制技术。本文依托四川仁沐新高速公路隧道路面工程,研究温拌改性沥青路的施工技术。

When paving the asphalt in the tunnel, due to the tightness of the environment, the smoke, dust and heat of the asphalt mixture can not be discharged in time, and the harmful gas covers the construction area for a long time. Warm mix modified asphalt technology is a pavement construction control technology in a closed environment for the purpose of reducing mixture production and construction temperature. This paper studies the construction technology of warm mix modified asphalt road based on the tunnel pavement project of Renmuxin expressway in Sichuan.
