在旧路面的铣刨以及复拌过程中,为了保证翻松材料的施工和易性,必须利用加热设备对路面进行高强度加热,容易导致沥青胶结料过热老化加剧,同时产生烟雾以及其他挥发物,对于现场施工作业人员的健康十分不利。因此,在就地热再生施工中引进具有降低混合料复拌及摊铺施工温度,并能够满足压实度及其他指标要求的温拌技术,可以有效的解决此类问题,对于促进就地热再生技术的推广应用也具有重要的作用。工程概况包茂高速公路鄂尔多斯段作为内蒙古矿产资源的重要输出通道,2004年通车以来由于重载车辆多,车流量大,出现了较为严重的高速公路路面车辙,严重影响了行车舒适安全,同时作为重要交通运输线,封闭施工难度较大。为了不影响高速公路的正常运营,采用路面热
In the old pavement milling and mixing process, in order to ensure the construction of work to ease the material and easy to use, heating equipment must be used to heat the road surface, easily lead to asphalt binder overheating aging, at the same time produce smoke and other volatile , For the site construction workers health is very negative. Therefore, it is an effective solution to such problems that the introduction of warm-mix technology, which can reduce the temperature of compounding and paving of the mixture and meet the compaction degree and other indexes, can be effectively used in the on-site thermal recycling project. The promotion and application also plays an important role. Project Profile Ordos section of Bao-Mao Expressway, as an important output channel of mineral resources in Inner Mongolia, has experienced serious road surface rutting due to the large number of overloaded vehicles and traffic flow since its opening in 2004, seriously affecting traffic safety and safety. Important transportation lines, closed construction more difficult. In order not to affect the normal operation of the highway, the use of road heat
