Municipal road asphalt ultra-thin bonding layer anti-reflection crack pavement structure and construction method thereof
The invention discloses a municipal road asphalt ultra-thin bonding layer anti-reflection crack pavement structure and a construction method thereof.The pavement structure comprises a grouting layer, an ultra-thin overlay layer, a stress absorption layer, a road panel layer and a base layer, and the ultra-thin overlay layer, the stress absorption layer, the road panel layer and the base layer are sequentially arranged from top to bottom; the grouting layer is arranged at the local positions between the road panel layer and the base layer and located on the two sides of the gap. The pavement structure has the beneficial effects that an active and passive joint defense mode is adopted to resist the reflection cracks of the cement board, the grouting layer belongs to an active mode to resist the reflection cracks of the cement board, and the ultra-thin overlay layer and the stress absorption layer belong to passive defense cement board reflection cracks, so that the durability of the pavement structure for resisting the reflection cracks of the asphalt ultra-thin bonding layer of the municipal road is improved; the service life of the ultra-thin overlay layer is prolonged, the maintenance cost is reduced, and the anti-reflection crack effect is good.
本发明揭露一种市政道路沥青超薄粘结层抗反射裂缝路面结构及其施工方法，路面结构包括注浆层，以及由上往下依次设置的超薄罩面层、应力吸收层、道路面板层和基层，道路面板层上形成有缝隙，注浆层设置在道路面板层和基层之间的局部位置，并位于缝隙的两侧。本发明的有益效果，采用主动式加被动式联防模式抵抗水泥板反射裂缝，注浆层属于主动式模式抵抗水泥板反射裂缝，超薄罩面层、应力吸收层属于被动防御水泥板反射裂缝，提高了市政道路沥青超薄粘结层抗反射裂缝路面结构的耐久性，延长超薄罩面层的使用寿命，降低养护成本，抗反射裂缝效果好。
