Abstract
The utility model provides an antiskid snow melting pavement structure layer, wherein a cold coated resin base layer is paved on the upper surface of a base course of a pavement, a hard inorganic gravel aggregate layer is paved on the upper surface of the cold coated resin base layer, and a snow melting seal layer is paved on the upper surface of the hard inorganic gravel aggregate layer, the cold coated resin base layer is 0.5mm to 2mm thick, the hard inorganic gravel aggregate layer is 0.5mm to 3mm thick, and the snow melting seal layer is 0.5mm to 1mm; the points of gravels in the hard inorganic gravel aggregate layer are exposed from the surface of the upper part of the snow melting seal layer. The antiskid snow melting pavement structure layer effectively improves the friction and the abrasive resistance of the pavement while solving the problems of easy snow accumulation and icing of roads in winter in such a manner of coating the pavement, and as a result, the danger of skidding on the pavement in winter is reduced and the service life of the pavement is prolonged.
Description
Technical field
The utility model belongs to highway construction technical field, is specifically related to a kind of antiskid snow melt road surface structare layer.
Background technology
In a lot of cities of northern China, due to winter climate cold, often produce large area road snow and do not change, cause vehicle to be difficult to pass through, traffic accident incidence significantly increases; In recent years, global extreme weather takes place frequently, and a lot of cities of south China also produce consecutive low temperature winter, there is sleet and snow ice weather in many places, sleet causes icy on road, the Duo Di highway existing vehicle slip continuous rear collision accident that occurs frequently, and part speedway is had to close section and is removed ice and snow.
The a large amount of accumulated snow in road surface in winter or low temperature ice-patch surface easily cause that traffic jam, highway stop transport, and the serious consequences such as socked-in, hinder for alleviating traffic, safeguard traffic safety, just can resume traffic after needing road pavement to clean in time the work such as deicing.Artificial deicing time and effort consuming, uses artificial snow removing mode also unrealistic for large area section, and machine deicing need be purchased professional deicing instrument in advance, waste HIGHWAY MAINTENANCE cost, and still need plenty of time work could recover road traffic.
Domestic and international a kind of advanced person's snow removing mode is the road surface special coating snow removing in active snow-clearing technique at present.This kind of snow removing mode is in the time of laying of roadway, mixes after just snow melt material being loaded to carrier material with mulseal, aqueous epoxy resins and curing compound, is sprayed onto on clean road surface, makes this road structure itself have the initiatively function of snow-melting and ice-breaking.
The most outstanding weak point of technical scheme of above-mentioned snow removing is that the ground friction coefficient after coating covers reduces, cause wheel easily smooth, braking distance increases, vehicle is under steam very easily because skidding the traffic accidents such as defective steering stabilizer, collision, overturning occur, especially in the winter time road opens ice in snow melt process, and frictional ground force reduces even more serious.On the other hand, top is low by the fast light photograph of antiskid coating of mortar making, under ultraviolet ray is irradiated for a long time, the very easily degradation with aging of epoxy resin of antiskid coating inside, thereby cause antiskid effect and coating life all can be greatly affected, make skid resistance pavement because application life is too short and do not possess practical application.
Summary of the invention
Friction factor that technical problem to be solved in the utility model is to overcome prior art is low, application life is short, easily produce the shortcomings such as traffic accidents, and the antiskid snow melt road surface structare layer of a kind of simple in structure, stable performance, safe and reliable, long service life is provided.
Addressing the above problem adopted technical scheme is: have cold painting type resin bottom at sub-surface upper surface making, cold painting type resin bottom upper surface making has the inorganic gravel aggregate layer of hard, the inorganic gravel aggregate layer of hard upper surface making has snow melt sealing, the thickness of described cold painting type resin bottom is 0.5～2mm, the thickness of the inorganic gravel aggregate layer of described hard is 0.5～3mm, the thickness of described snow melt sealing is 0.5～1mm, and snow melt sealing upper face is exposed at the gravel tip in the inorganic gravel aggregate layer 3 of described hard.
Antiskid snow melt road surface structare layer of the present utility model freezes and effectively raises frictional resistance and the abrasion resistance on road surface in a difficult problem to have solved Louis, road in winter accumulated snow in the mode of road surface coating, reduce the danger of slipperiness on roads in winter, extended the application life on road surface.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but the utility model is not limited only to following embodiment.
Embodiment 1
In Fig. 1, antiskid snow melt road surface structare layer of the present utility model is made up of cold painting type resin bottom 2, the inorganic gravel aggregate layer 3 of hard, snow melt sealing 4 from the bottom to top.
On basal plane 4, evenly smear cold painting type resin bottom 2, the thickness of cold painting type resin bottom 2 is 0.5mm, because cold painting type resin bottom 2 friction factor are low, cling property is poor, the inorganic gravel aggregate layer 3 of upper surface spreading hard after the cold painting type resin bottom 2 that making is completed solidifies, gravel aggregate uniform spreading is sprinkling upon to cold painting type resin bottom 2 and guarantees to cover completely, gravel aggregate is absorbed on not completely crued cold painting type resin bottom 2 and forms the inorganic gravel aggregate layer 3 of hard, the thickness of the inorganic gravel aggregate layer 3 of hard is 0.5mm, inorganic gravel aggregate layer 3 thickness of hard are larger, part is invaded and is moistened in cold painting type resin bottom 2, the tip portion of top gravel aggregate is outside exposed, cold painting type resin bottom 2 solidifies after combination completely with the inorganic gravel aggregate layer 3 of hard, at the inorganic gravel aggregate layer 3 upper surface making snow melt sealings 4 of hard, the thickness of snow melt sealing 4 is 0.5mm, leave standstill and solidify.Some is exposed to snow melt sealing 4 upper surface outsides gravel aggregate tip in the inorganic gravel aggregate layer 3 of hard in intermediate layer, make the utility model antiskid snow melt road structure in possessing good snow-melting and ice-breaking function, effectively improve friction factor and the anti-wear performance on road surface, guaranteed the safety on road surface and longer application life.
The antiskid snow melt road surface structare layer of the present embodiment is: at the cold painting type of the basal plane even blade coating of 4 upper surface resin bottom 2, the thickness of cold painting type resin bottom 2 is 1mm, the inorganic gravel aggregate layer 3 of cold painting type resin bottom 2 upper surface making hard, the thickness of the inorganic gravel aggregate layer 3 of hard is 3mm, the inorganic gravel aggregate layer 3 upper surface making snow melt sealings 4 of hard, the thickness of snow melt sealing 4 is 2mm.
The antiskid snow melt road surface structare layer of the present embodiment is: at the cold painting type of the basal plane even blade coating of 4 upper surface resin bottom 2, the thickness of cold painting type resin bottom 2 is 0.75mm, the inorganic gravel aggregate layer 3 of cold painting type resin bottom 2 upper surface making hard, the thickness of the inorganic gravel aggregate layer 3 of hard is 2mm, the inorganic gravel aggregate layer 3 upper surface making snow melt sealings 4 of hard, the thickness of snow melt sealing 4 is 1mm.
Also can design the antiskid snow melt road surface structare layer of another concrete structure according to above-mentioned principle, but all within protection domain of the present utility model.
