Solar road pavement structure

Abstract

The invention discloses a solar road pavement structure. The solar road pavement structure comprises a foundation stabilization layer, a moisture-proof layer, a regulation layer, a stress buffer layer, a composite photovoltaic layer and a pavement layer from bottom to top, an electric power storage device is arranged on a road side, wherein a heating element and a heat sensor are buried in the pavement layer, the electric power storage device is connected with the composite photovoltaic layer and the heating element, a second solenoid valve is arranged on a circuit between the electric power storage device and the composite photovoltaic layer, a first solenoid valve is arranged on a circuit between the electric power storage device and the heating element, the pavement structure further comprises a control unit, and the control unit is electrically connected with the electric power storage device, the first solenoid valve, the second solenoid valve and the heat sensor. On the basis of intensive usage of land and space, solar photovoltaic panels are laid on the road to generate electricity, generated electric power can be utilized to heat the pavement in the winter season, freezing and snow accumulation on the pavement are prevented, the driving safety performance of vehicles is improved, and at the same time, after conversion and storage, the electric power can be integrated to grids or supplied to traffic lights, monitoring devices, charging of electric vehicles and the like for usage.

Description

[0001] Technical field: [0002] The invention relates to a new type of road pavement structure, in particular to a solar road pavement structure. [0003] Background technique: [0004] The pavement structure is mainly divided into cushion layer, base layer, and surface layer. According to the different surface materials, it can be divided into cement concrete pavement, asphalt concrete pavement and sand-gravel pavement. Among them, the sand-gravel pavement is easy to raise dust due to poor road surface smoothness and rain. It is seldom used because it is muddy and requires frequent feeding and maintenance. Judging from the most commonly used cement pavement structures and asphalt pavement structures, there is a phenomenon of icing and snow accumulating in the rain and snow in winter, causing the vehicle to slip when driving and greatly reducing the driving safety. In addition, cement pavement has long maintenance time, affecting traffic, and high driving noise. Asphalt pavement is...

AI Technical Summary

Problems solved by technology

Judging from the most commonly used cement pavement structures and asphalt pavement structures, there are phenomena of freezing and snow accumulation in rainy and snowy weather in winter, which will cause the vehicle to slip when driving and greatly reduce driving safety.

Moreover, cement pavement has defects such as long maintenance time, affecting traffic, and high driving noise; asphalt pavement is prone to water damage, poor thermal stability, easy to be brittle in winter, softened in summer, poor in aging resistance, and difficult to guarantee durability. It is easy to form defects such as ruts, and because the asphalt pavement is black, it is easy to absorb heat and become an important factor for global warming
