Reflection crack resistant white-to-black pavement structure and implementation method
The invention belongs to the technical field of road engineering, and particularly relates to a reflection-crack-resistant white-to-black pavement structure and an implementation method, and the reflection-crack-resistant white-to-black pavement structure comprises an old cement pavement, a modified asphalt waterproof bonding layer, a large-particle-size macadam layer, a high-viscosity asphalt macadam layer, a high-modulus asphalt concrete layer and a wearing layer. The modified asphalt waterproof bonding layer is arranged at the upper end of the old cement pavement, the large-particle-size gravel layer is arranged at the upper end of the modified asphalt waterproof bonding layer, the original strength of the old cement pavement is fully utilized, an old cement slab does not need to be crushed or removed, and the strength of large gravel is high enough under the boundary constraint condition. Through combination of materials and structures, the problem of reflection cracks of the white-to-black pavement is solved, the asphalt mixing process is reduced, energy conservation and emission reduction are achieved, the manufacturing cost is low, and the good market popularization value is achieved.
本发明属于道路工程技术领域，具体为一种抵抗反射裂缝的白改黑路面结构及实施方法，包括旧水泥路面、改性沥青防水粘结层、大粒径碎石层、高粘沥青碎石层、高模量沥青混凝土层和磨耗层，其特征在于，所述改性沥青防水粘结层设置在旧水泥路面的上端，所述大粒径碎石层设置在改性沥青防水粘结层的上端，充分利用旧水泥路面的原有强度，无需对旧路水泥板破碎或清除，利用大碎石在有边界约束的条件下强度足够高的特性，通过材料与结构的结合，解决白改黑路面反射裂缝问题，减少沥青拌合工艺，节能减排，造价低，具有良好的市场推广价值。
