Road heating mat for melting ice and snow and pavement construction method thereof

Abstract

The invention provides a road heating mat for melting ice and snow and a pavement construction method thereof. The heating mat is arranged on an interface surface of an upper surface layer and a middle surface layer, is preformed by a heat insulation grid and heating cables, and can be divided into a straight mat and a bend mat according to the set shape of the heat insulation grid; the interlayer overall size occupancy rate and the field pavement power of the heating mat are utilized for synchronously adjusting the set parameters of the heat insulation grid, so that the interlayer stability can be effectively improved; the heating cables are arranged along grid bars of the heat insulation grid, so that the heat utilization ratio of the heating cables can be maximized. According to the construction method provided by the invention, through paving a rail, the heating mat can be effectively prevented from being crushed, pulled to be rolled up or pushed to slide so as to be damaged; through spraying emulsified asphalt for two times, fixing the heating mat through staple bolts, and setting the grinding times according to the interlayer overall size occupancy rate of the heating mat, the interlayer stability of the road requiring melting ice and snow can be effectively improved, the road damage is reduced, and the service life of the road requiring melting ice and snow is prolonged.

Description

technical field [0001] The invention belongs to the field of urban roads and disaster prevention, and more specifically relates to a heat-generating floor mat for roads and a road surface construction method thereof, which are used to quickly melt snow and ice on snow-covered or icy road surfaces, and through various construction Measures are taken to enhance the interlayer contact force of the road structure, and to minimize the damage and use of the original road while exerting the function of melting ice and snow pavement. Background technique [0002] Snow and icing on the road in winter cause a lot of inconvenience for people to travel, and at the same time have a serious impact on the smoothness of the road and driving safety. In ice and snow weather, the adhesion ability of the road surface is greatly reduced, which is extremely unfavorable to the driving dynamics and safety of the vehicle. The existing commonly used road surface snow melting and deicing methods main...

Problems solved by technology

[0004] At present, the more mature heating cable laying methods mainly include the following two types: one is notching, and the carbon fiber wire is embedded in the middle surface layer by the groove method, which does not affect the paving and rolling construction of the upper layer, and has a great impact on the interlayer adhesion. The influence of the junction is small, but the depth and width of the groove need to be determined according to the selected carbon fiber heating wire specifications, and the structure of the middle layer itself is destroyed, which increases the construction workflow and cannot be applied to various types of cables; One is to make heating cable grids for laying, but the existence of heating cables and grids directly affects the bonding between layers, which is easy to cause the asphalt surface to move and wrap, shortening the service life of the road. Most of the roads on the market The prefabricated grid is made of high-strength non-heat-insulating material. To facilitate construction and binding, the heating cables are mostly placed in the space of the grid and arranged in a serpentine shape. The heat transfer is quite scattered, which takes a long time and consumes a lot of energy.

These existing methods are not easy to lay cables, and damage such as cable displacement will occur in advance during the construction process; at the same time, the pavement structure has too many layers, which affects the overall stability of the pavement and the mechanical strength between layers, especially when heavy vehicles brake suddenly. Under certain conditions, the displacement between the pavement layers may occur, which greatly affects the service life of the pavement
