High-content rubber modified asphalt permanent pavement structure
The invention relates to the field of road building materials, and discloses a high-mixing-amount rubber modified asphalt permanent pavement structure which sequentially comprises an upper surface layer, a waterproof bonding layer, a middle surface layer, a lower surface layer and an anti-fatigue layer from top to bottom, and the upper surface layer, the middle surface layer, the lower surface layer and the anti-fatigue layer all comprise high-mixing-amount rubber modified asphalt concrete layers. According to the high-mixing-amount rubber modified asphalt concrete layer of the upper surface layer, the mixing amount of rubber ranges from 30% to 35% by mass, the mixing amount of the middle surface layer ranges from 40% to 45% by mass, and the mixing amount of the lower surface layer and the anti-fatigue layer ranges from 50% to 55% by mass. The waterproof bonding layer is a fiber reinforced rubber modified asphalt waterproof bonding layer; the middle surface layer comprises two groups of high-modulus rubber modified asphalt concrete layers and wheel-sticking-free emulsified asphalt sticky layers which are sequentially stacked. According to the pavement structure provided by the invention, the anti-rutting performance and the bearing capacity are effectively improved, and the anti-fatigue performance of the pavement is improved; the crack resistance, the fatigue resistance and the durability of the permanent pavement are improved.
本发明涉及道路建筑材料领域，其公开了一种高掺量橡胶改性沥青永久性路面结构，自上而下依次包括：上面层、防水粘结层、中面层、下面层和抗疲劳层，所述上面层、中面层、下面层和抗疲劳层均包括高掺量橡胶改性沥青混凝土层，所述上面层的高掺量橡胶改性沥青混凝土层，其按照质量百分比橡胶的掺入量范围是30％‑35％，所述中面层的掺入量范围是40％‑45％，所述下面层和抗疲劳层的掺入量范围是50％‑55％；所述防水粘结层为纤维加强型橡胶改性沥青防水粘结层；所述中面层包括两组依次叠放的高模量橡胶改性沥青混凝土层和不粘轮乳化沥青黏层。本发明提供的路面结构，有效提高抗车辙性能和承载能力，提高路面抗疲劳性能；提高永久性路面的抗裂、抗疲劳、耐久性能。
