Design and construction method of anti-crack heavy traffic road asphalt pavement
The invention relates to a design and construction method of an anti-crack heavy traffic road asphalt pavement, belongs to the technical field of road engineering, solves the problem of crack of the existing road asphalt pavement and the problem of defects in the pavement structure, and is particularly suitable for heavy traffic grade roads. A design and construction method of an anti-crack heavy traffic road asphalt pavement comprises the steps that a pavement structure is determined based on the bearing capacity of the pavement, and the pavement structure comprises a surface wearing layer, a high-modulus asphalt concrete layer, a base layer, a subbase layer and the like from top to bottom; and then determining a construction sequence, sequentially paving the subbase layer, the base layer, the fiber anti-crack modified asphalt waterproof bonding layer and the high-modulus asphalt concrete layer, and then paving the middle connecting layer and the surface wearing layer, or directly paving the surface wearing layer. The beneficial effects that the anti-cracking performance of a heavy traffic road is improved, the bearing capacity is improved, the pavement thickness is reduced, and the service life is prolonged are achieved.
本发明涉及一种抗裂型重载交通公路沥青路面的设计和施工方法，属于道路工程技术领域，解决了现有公路沥青路面出现裂缝的病害问题，以及路面结构中存在的不足的问题，且特别适用于重载交通等级公路。一种抗裂型重载交通公路沥青路面的设计和施工方法，包括基于路面的承载能力确定路面结构，从上到下包括表面磨耗层、高模量沥青混凝土层、基层及底基层等；然后确定施工顺序，包括依序铺筑底基层、基层、纤维抗裂型改性沥青防水粘结层、高模量沥青混凝土层,然后铺筑中间联结层和表面磨耗层，或直接铺筑表面磨耗层。实现了重载交通公路提升抗裂性能，改善承载能力，减薄路面厚度，延长使用寿命的有益效果。
