Problems solved by technology
[0006] In order to make up for the deficiencies in the prior art, the surface temperature of the highway pavement that solves the road surface construction is likely to be high in summer due to the high temperature, which will easily cause tire blowouts and other phenomena during the driving of the car, and traffic accidents are prone to occur. The temperature is too low, the road surface is easy to freeze, resulting in slippery, driving brake failure, leading to the occurrence of safety accidents, a road pavement structure and a construction method for road pavement proposed by the present invention

The invention belongs to the technical field of road surface construction, and specifically relates to a road, road surface structure and a road surface construction method, including a road surface layer; the road surface construction of the present invention is provided with a temperature control layer, and the water in the temperature control layer is located at the bottom of the road surface layer , when the weather is hot, the water in the temperature control layer below will absorb the heat generated on the surface of the pavement layer to achieve the effect of cooling the pavement layer; when the weather is cold, the water in the temperature control layer below will transfer the temperature to the The surface of the pavement layer keeps the surface of the pavement layer in a state that is not easy to freeze. A temperature control layer is provided between the upper concrete layer and the lower concrete layer to maintain a stable temperature for the pavement layer and increase the service life of the pavement layer. From The water inlet end can collect rainwater to enter the inside of the temperature control layer, and the excess water in the temperature control layer is discharged from the water outlet, so as to collect rainwater and replace the water inside the temperature control layer by the collected rainwater.
Description
technical field [0001] The invention belongs to the technical field of pavement construction, in particular to a highway pavement structure and a construction method of the highway pavement. Background technique [0002] Pavement refers to a layered structure that is paved with various road construction materials on the road subgrade and directly bears the vehicle load. A pavement with good quality should have sufficient strength and good stability, and its surface should meet the requirements of smoothness, compactness and anti-skidding. The pavement structure consists of surface layer, base layer and cushion layer. [0003] Concrete, sand, gravel and other devices need to be used in the construction of highway pavement, and oxidation is required during construction, and the surface of highway pavement is often paved with an asphalt layer. [0004] However, in the prior art, the road surface is prone to higher surface temperature due to higher temperature in summer, which...
