Ultrathin rubber asphalt wearing layer for pavement
The invention discloses an ultrathin rubber asphalt wearing layer for a pavement. The wearing layer comprises the following components: a mineral mixture and rubber asphalt, wherein the mineral mixture comprises coarse aggregate, fine aggregate and mineral powder; wherein the coarse aggregate is basalt macadam, and the particle size of the coarse aggregate comprises basalt macadam within two ranges of 4-7 mm and 7-11 mm; the fine aggregate is limestone macadam, and the particle size range is 0-4 mm; wherein the mineral powder is limestone mineral powder; waste tire rubber powder and a small amount of other assistants are used as auxiliary materials, crushing and pressing are carried out, the process of preparing novel rubber and plastic under the condition of 260 DEG C is mainly based on the physical effect, good melt blending characteristics are shown by adding the rubber powder, the high-temperature stability of a wearing layer is improved, and the pit aging capacity is enhanced; meanwhile, a large amount of waste tire rubber powder can be consumed when the rubber asphalt pavement is used for construction, waste tire resource utilization is achieved, and black pollution is reduced.
本发明公开了一种路面超薄橡胶沥青磨耗层，该磨耗层包括以下组分：矿质混合料、橡胶沥青；所述矿质混合料包括粗集料、细集料、矿粉；所述粗集料为玄武岩碎石，粒径包括4‑7mm，7‑11mm两种范围的玄武岩碎石；细集料为为石灰岩碎石，粒径范围0‑4mm；所述矿粉为石灰岩矿粉；利用废旧轮胎橡胶粉并辅以少量其它助剂,粉碎，压制，在260℃条件下制备新型橡塑过程以物理作用为主,通过加入橡胶粉显示出良好的熔融共混特性,增加磨耗层的高温稳定性，增强坑老化能力；同时使用橡胶沥青路面建设可消耗大量废轮胎橡胶粉,实现废轮胎资源化利用,降低黑色污染。
