Road surface ultra-high performance surface seal coat and construction method thereof
The invention discloses a road surface ultra-high performance surface seal coat and a construction method thereof, and belongs the technical field of road surface construction. The construction method comprises the following steps: firstly, synchronously spreading high-elastic modified asphalt and crushed stone material, and then spreading high-viscosity high-elasticity emulsified asphalt, wherein each square meter of the seal layer includes 0.8-1.2 parts by mass of the high elastic modified asphalt, 0.5-0.8 part by mass of the high-viscosity high-elasticity emulsified asphalt, and 4.3-5.5 parts bymass of crushed stone material, and finally curing for 2-4 hours. The road surface ultra-high performance surface seal coat obtained through the construction method of the road surface ultra-high performance surface seal coat is remarkable in waterproof and water retention effect, ruts are not prone to being generated, the influence of weather environment limitation on construction is small, construction can be conducted in low-temperature or rainy and snowy days, the construction period is short, the construction cost is low, and the problems that an existing road surface super-surface seal coat is greatly limited by weather environment, and is long in maintenance time and long in construction period can be solved.
本发明公开了道路路面施工技术领域内的一种道路路面超高性能表处封层及施工方法，包括先同步撒布高弹改性沥青、碎石料，再撒布高粘高弹乳化沥青，每平方米所述封层中高弹改性沥青质量份数为0.8‑1.2份，高粘高弹乳化沥青质量份数为0.5‑0.8份，碎石料质量份数为4.3‑5.5份，最后养护2‑4小时。本发明提供的一种道路路面超高性能表处封层施工方法施工得到的道路路面超高性能表处封层防水、保水效果显著，不易产生车辙，施工受到天气环境的限制影响小，低温、雨雪天均可施工，施工周期短，施工成本低，能够解决现有路面超表处封层受到天气环境限制大，养护时间长，施工周期长的问题。
