Embodiment Construction
[0014] The tensile crack-resistant pavement with cellular reinforcement is composed of surface layer 1 and cellular reinforcement 2. Wherein, the material of surface layer 1 is dense asphalt concrete. The honeycomb reinforcement 2 is a network structure composed of a plurality of regular hexagonal frames with a circumscribed circle diameter of 60 mm. The cross-sectional area of the frame bars that constitute the regular hexagonal frame is 10mm 2 , The frame material is low-pressure polyethylene engineering plastics. The honeycomb reinforcement 2 is in the surface layer 1, and the upper surface of the honeycomb reinforcement 2 is 15mm away from the road surface behind the cover.

The invention relates to the technical field of urban traffic, in particular to a honeycomb tendon drawing type anti-crack road surface. The road surface consists of a surface layer and a honeycomb tendon. The material of the surface layer is compact type bituminous concrete. The honeycomb tendon is a netty structure which is formed by a plurality of regular hexagon frames with the circumcircle diameter of 40-60mm. The cross sectional area of each frame edge formed into the regular hexagon frames is 6-10 mm<2>, the material of the frame edge is low-pressure polyethylene engineering plastics. The honeycomb tendon is arranged in the surface layer, and the distance from the upper surface of the honeycomb tendon to the covered road surface is 10-15mm. The honeycomb tendon drawing type anti-crack road surface can greatly reduce the frequency for the maintainance and the constructure of the road surface and the corresponding investment, and can greatly prolong the service life of the road surface.
Description
technical field [0001] The invention relates to the technical field of urban traffic, in particular to a tensile crack-resistant pavement with cellular reinforcement. Background technique [0002] Asphalt-based semi-rigid materials are widely used in highway pavement materials in my country. Because the ductility of the asphalt used in the existing asphalt pavement is generally not high, and at the same time, the asphalt pavement is prone to cracks due to the temperature difference between summer and winter, day and night, and the impact of motor vehicle tires, which affects the speed of the highway. Quality and service life of roads. Among the existing expressway cracks, there are three types of cracks, irregular cracks, and longitudinal and transverse cracks, among which cracks are the most prominent. Cracks, also known as network cracks, are criss-crossed, resembling turtle-like network cracks, and the road surface is divided into cross cracks with a block size greater ...
