Description

Technical Field

[0001] The utility model relates to the field of pavement structures, in particular to a rigid-flexible composite honeycomb long-life pavement structure capable of melting snow and ice. Background Art

[0002] Traditional rigid-flexible composite pavement refers to a pavement whose surface layer is composed of two structural layers with different material types and mechanical properties. It generally refers to a composite pavement mainly composed of honeycomb prefabricated blocks and asphalt concrete. Asphalt concrete composite pavement gives full play to the advantages of different pavement materials. The high-strength rigid blocks are used as the rigid foundation to improve the bearing capacity of the asphalt pavement, which can meet the requirements of heavy load, overload and other traffic load conditions. The asphalt concrete surface layer is used to improve and enhance the use quality of the concrete pavement surface, which can meet the requirements of high-speed driving performance of automobiles and is easy to repair and maintain. This rigid-flexible composite pavement can meet the requirements of the durability and longevity of the pavement structure under heavy load traffic conditions to a certain extent.

[0003] However, in winter, snow and ice on this traditional rigid-flexible composite pavement will have a serious impact on the smooth flow of traffic and driving safety. Snow and ice greatly reduce the adhesion coefficient of the road surface, causing the car to slip, significantly extend the braking distance, and even brake failure and loss of control, thus causing serious traffic accidents. Therefore, in order to ensure smooth roads and driving safety, avoid or reduce traffic accidents, and improve road capacity and operational efficiency, measures must be taken to remove ice and snow on the road surface. The technology of removing ice and snow or using ice and snow melting on this traditional rigid-flexible composite pavement mainly relies on external snow melting and ice removal technology on the road surface, which includes manual method, mechanical method and snow removal agent method; geothermal heat conduction pavement automatic snow melting and ice removal technology came into being, and the layout method of geothermal heat conduction pipes on asphalt pavement is crucial in this technology.
