西藏冷补料的工艺原则解析

发布日期:2019-07-22 作者: 点击:

西藏冷补料冷补料智胜彩票施工应选对冷补料。选择合理使用时可适当延长病害修补区养生时间,使其有足够的初始强度应对通行。冷补料级配的真对性原则大化的贴近原路面基配; 再生冷补料符合当地环境,节约资源,利于环保。冷补料施工时应注意重点工艺。冷补料施工的工艺原则是认真选料、杜绝漏洞、绝对防水、分层填料、保证压实、适度养生。在行车和空气的作用下使一部分添加剂挥发,沥青逐步变稠,冷补混合料颗粒之间的分布更加紧密,空隙率减少,矿料相互的黏结更牢固。


混合料的密度增大,对路面软的感觉会逐渐消失,这一过程需要7—10天时间(如果沥青砂铺筑过厚,固化时间还要相应延长.夏季施工,固化时间会不超过10天)。对冷补料评价方法做了适当改进,效仿国外评价体系,此次所用旋转黏度试验可评价冷补液的黏度及均匀性,冷补液对骨料的黏附效果采用纸迹试验评价,而评价沥青冷补料施工性能时放弃了常用的室内马歇尔试验,而采用对试验路进行修补的方式,评价更加直观。
