长大隧道沥青路面施工技术研究

Research on Construction Technology of Asphalt Pavement in Long Tunnel

长大隧道内空间有限,路面施工中沥青混合料的温度高、烟尘大,施工比较困难,难以保证工程质量。连霍国家高速公路(G30)兰州绕城南段(G3001)隧道沥青路面工程采用采用阻燃沥青,本文分析与研究沥青路面平整度的控制技术及长大隧道路面沥青混合料技术在施工中的应用。

The space of long tunnel is limited,the temperature of asphalt mixture in pavement construction is high,the smoke is large,the construction is difficult,and it is difficult to ensure the engineering quality.The asphalt pavement project of Lianhuo National Expressway(G30)Lanzhou Ring City South Section(G3001)tunnel adopts flame retardant asphalt.This paper analyzes and studies the control technology of asphalt pavement smoothness and the application of asphalt mixture technology of long tunnel pavement in construction.
