阻燃沥青混凝土在储运使用过程中常发生严重的离析问题,通常储存时间不能超过48 h。且试验表明,在沥青中加入阻燃剂后严重影响了沥青的性能。在沿江高速公路中有4条隧道应用了一项隧道沥青混凝土路面新型阻燃改性技术,将一种特制的阻燃改性剂直接添加到沥青混合料中,并对其进行阻燃改性,在不影响沥青混合料路用性能的基础上显著提高沥青混凝土路面的阻燃性能。
Flame-retardant asphalt concrete storage and transportation in the process of using often serious separation problems, usually storage time can not exceed 48 h. Experiments show that the addition of flame retardant in asphalt seriously affects the performance of asphalt. In the highway along the Yangtze River has 4 tunnels applied a new asphalt fire retardant modified tunnel technology, a special flame retardant modifier added directly to the asphalt mixture, and its flame retardant modified , On the basis of not affecting the road performance of asphalt mixture, significantly improve the flame retardant performance of asphalt concrete pavement.
