Nano-toughened rubber asphalt Kaipu pavement structure and construction method thereof
The invention discloses a nano-toughened rubber asphalt Kaipu pavement structure which comprises a bottom layer, a middle layer and a surface layer which are sequentially arranged from bottom to top; the surface layer is made of a modified emulsified asphalt thin slurry mixture, and the laying thickness of the surface layer is 1cm; the middle layer and the bottom layer are respectively paved with a broken stone sealing layer with the thickness of 1-2cm, and a cementing material of the broken stone sealing layer is toughened rubber asphalt. The pavement structure is proper in viscosity, the problems that in the prior art, high-viscosity rubber asphalt is difficult to process and not convenient to distribute during construction are solved, the excellent stress absorption capacity of the rubber asphalt is fully utilized, the diseases of reflection cracking and rutting are greatly improved, meanwhile, due to the surface layer thin slurry mixture, the pavement has excellent waterproofness, flatness and skid resistance, construction is convenient, the environment-friendly advantage is high, and the Kaipu pavement structure can be used as pavement surface layers of newly-built and rebuilt highways of various traffic grades.
本发明公开了一种纳米增韧橡胶沥青开普路面结构，包括从下到上依次设置的底层、中间层、表层；表层采用改性乳化沥青稀浆混合料，表层铺设厚度为1cm；中间层和底层均铺设厚度为1‑2cm碎石封层，碎石封层的胶结料采用增韧橡胶沥青。本发明路面结构粘度适宜，解决了现有技术中高粘度橡胶沥青加工困难，不便于施工时洒布的问题，通过充分利用橡胶沥青优良的应力吸收能力，大大改善反射开裂和车辙的病害，同时表层稀浆混合料使路面具有优异的防水性、平整度和抗滑性，便于施工，具有较高的环保优势，本发明开普路面结构可用作各种交通等级新建、改建公路的路面面层。
