The invention relates to an asphalt concrete pavement maintenance structure and method. The asphalt concrete pavement maintenance structure comprises a repair groove, the repair groove is formed in anoriginal road layer, a repair base layer and a repair surface layer are sequentially arranged in the repair groove from bottom to top, the bottom of the inner wall of the repair groove is fixedly connected with a supporting table, and the supporting table is integrally connected with the original road layer; and a reinforcement cage ring is embedded in the repair base layer and located on the upper portion of the supporting table, and the repair base layer is formed by pouring concrete. The structure has the effect of prolonging the service life of the maintained asphalt concrete pavement. The asphalt concrete pavement maintenance method comprises the following steps: digging a containing groove, a first clamping groove and a repairing groove, and mounting a mounting part and a rib plate;binding a reinforcement cage ring, pouring concrete, paving an anti-cracking net, and hardening to obtain the repair base layer; and continuously laying asphalt concrete to obtain the repair surfacelayer. The effect of simple construction is achieved.
Description
technical field [0001] The application relates to the field of pavement maintenance, in particular to an asphalt concrete pavement maintenance structure and a method thereof. Background technique [0002] With the increase of traffic vehicles, the structural performance of asphalt pavement gradually deteriorates with the repeated action of traffic load and the change of environmental conditions, especially at the intersection of roads, where the frequency of vehicles passing by and the effect of vehicle load are more, it is easier to damage. [0003] It is known that the repair of damaged pavement is usually restored according to the original road design scheme. In the design scheme of asphalt concrete pavement, the conventional method is to use flexible subbase (graded gravel) + semi-rigid base (cement stabilized gravel) + asphalt way of topping. [0004] The flexible subbase and semi-rigid base need layered rolling construction, and the post-construction settlement is al...
