Description
Technical Field
The invention relates to the technical field of pavement markers, in particular to a novel pavement luminous marker embedding method.
Background
The luminous identification is buried at the zebra crossing position of the urban road intersection, so that a 'low head group' can be effectively warned, and the traffic accident rate of the intersection is reduced. The pavement case and the field investigation of the existing pavement light-emitting device find that the pavement at the concrete groove position where the pavement mark is originally embedded is easy to generate larger cracks or even cracks, the pavement evenness and the service performance are seriously influenced, and the problem of water drainage of the mark pavement groove is difficult to solve. Patent numbers: 201910053729.8 the light emitting device is buried by making a groove with a certain size in the road surface, positioning the light emitting device on a straight line, and then pouring concrete and compacting. The tensile anti-cracking performance of the road surface treated by the construction method at the concrete groove is poor, and in rainy seasons, rainwater on the road surface is easy to leak into the side seam of the concrete groove wall. When a vehicle passes through the concrete trough pavement, a large dynamic impact load can be generated, and water leakage in cracks instantly generates extremely strong water pressure to splash and bring out broken stone particles from the cracks, so that gaps are generated between the pavement and the base layer at the concrete trough. Under the repeated action of the cyclic load of the vehicle, the damage degree of the road surface at the concrete groove position where the luminous mark is embedded will be increasingly aggravated, and the road surface is easy to crack in winter and summer and is easy to bulge in summer, especially in winter and summer. On the other hand, the road surface embedding position of the luminous mark is special and is generally positioned at the intersection of the urban road. The traffic flow is large, the channeling of the vehicle is obvious, and the horizontal braking force generated by starting and braking further aggravates the road surface diseases. Once the damage occurs, the traffic is closed for maintenance, and the urban traffic jam is adversely affected. In consideration of building energy conservation and pavement service performance, a certain treatment method is adopted to enhance the tensile anti-cracking performance of the pavement at the concrete groove and the drainage performance of the concrete groove.
