Composite interlayer layer for inverted semi-rigid base asphalt pavement structure layer combination
The invention relates to a composite interlayer fault for inverted semi-rigid base asphalt pavement structure layer combination, and belongs to the technical field of road engineering. The composite intersectional layer comprises the following components in parts by weight: 50-70 parts of gravel with the particle size of 4-6cm, 5-20 parts of sand and 20-40 parts of cement emulsified asphalt sand grain type concrete. The composite interfault can block upward reflection of cracks of the semi-rigid base, no reflection cracks are generated in the asphalt pavement, and meanwhile, the compression-resistant resilience modulus of the interfault is improved, so that the rutting resistance of the asphalt pavement is equivalent to that of an asphalt pavement in a continuous system structure layer combination of the asphalt pavement with the semi-rigid base.
本发明涉及一种用于倒装式半刚性基层沥青路面结构层组合的复合间断层，属于道路工程技术领域。本发明的复合间断层包括以下组分及重量份：粒径4cm～6cm碎石50～70份、砂5～20份、水泥乳化沥青砂粒式混凝土20～40份。该复合间断层能阻断半刚性基层裂缝向上反射，在沥青路面中不产生反射裂缝，同时提高间断层的抗压回弹模量，使沥青路面的抗车辙性能与半刚性基层沥青路面连续体系结构层组合中的沥青路面相当。
