Ultrathin overlay asphalt mixture, preparation method thereof and application in pavement maintenance ultrathin overlay
The invention discloses an ultrathin overlay asphalt mixture, a preparation method thereof and application in pavement maintenance ultrathin overlay. The mixture comprises the following components in percentage by mass: 93.533%-93.875% of aggregate, 5.914%-6.267% of matrix asphalt and 0.2%-0.211% of chloroprene rubber. The mixture has the beneficial effects that the anti-cracking performance, the water damage prevention function, the anti-sliding performance, the high and low temperature stability function, the interlayer shear resistance function, the durability function and the like of the ultra-thin overlay are improved. The construction cost of the thin overlay can be lower than that of a traditional thin overlay while the road maintenance requirement is met, construction is more convenient and faster, the paving and compacting time is shortened, and traffic can be opened earlier.
本发明揭露一种超薄罩面沥青混合料及其制备方法和路面养护超薄罩面中的应用，混合料包括下述质量百分比的组份：集料93.533％‑93.875％、基质沥青5.914％‑6.267％和氯丁橡胶0.2％‑0.211％。本发明的有益效果，具有提升超薄罩面的抗裂性能、防水损害功能、抗滑性能、高低温稳定功能、层间抗剪功能和耐久功能等优点。在满足道路养护要求的同时能使薄层罩面的造价相对于传统薄层罩面更低、施工更加方便快捷，缩短了摊铺压实时间，能更早的开放交通。
