Abstract

The invention relates to the technical field of road construction, and discloses an anti-cracking asphalt concrete composite pavement structure. The pavement structure comprises a macadam roadbed layer, a supporting layer flatly laid on the macadam roadbed layer, a concrete layer flatly laid on the supporting layer and a pavement layer flatly laid on the concrete layer. The supporting layer comprises a steel frame horizontally placed above the gravel roadbed layer and a plurality of supporting rods horizontally arranged in the steel frame, the two ends of each supporting rod are fixedly connected with the steel frame, and the height of the supporting rods is equal to that of the frames. The asphalt concrete composite pavement structure has excellent loading performance and cracking resistance, so that the service life of an asphalt concrete pavement is prolonged.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an anti-cracking asphalt concrete composite pavement structure. Background technique [0002] The cracking of asphalt concrete pavement is one of the main diseases of the pavement. Due to poor pavement design or construction reasons, the structural layer itself is not strong enough to adapt to the increasing traffic volume and axle load, resulting in strength cracks, which generally manifest as longitudinal cracks at first. , and then develop into network cracks, this type of cracks produced by the load is common in the middle and low-grade roads and some high-grade lanes with serious overloading, and belongs to the load cracks. For most grade highways in our country, due to the generally used semi-rigid base, there is enough strength, this kind of load crack is not the main one, on the contrary, another kind of crack, that is, non-load crack, is ubiquitous, which has c...
