Abstract
A photo-thermal reflection type asphalt concrete pavement structure for reducing the temperature of pavement comprises a pavement layer (1) and a photo-thermal reflection type coating (2); the photo-thermal reflection type coating (2) is brushed or sprayed on the upper surface of the pavement layer (1); and an antiskid aggregate layer (3) is spread on the photo-thermal reflection type coating (2). The utility model has high photo-thermal reflectivity, thereby increasing the heat absorptivity of the pavement, reducing the temperature of the pavement and solving the wheel rutting problem of the pavement. The pavement also has the advantages of good wearing resistance, strong skid resistance, long service durability and the like.
Description
One, technical field
The utility model relates to the highway construction road structure, especially a kind of photothermal reflectance type asphalt concrete pavement structure that reduces pavement temperature.
Two, background technology
Along with economic development, technological progress, the construction quantity of road increases year by year.Flexible pavement is owing to have advantages such as planeness height, noise is little, road-ability is good, and therefore, particularly in the high-grade highway, major part all adopts the form of flexible pavement at newly-built highway.But well-known, pitch is a kind of heat-absorbing material, and its solar heat absorptivity is very high, reaches 0.85～0.95.In summer, under the lasting heat radiation effect of the sun, a large amount of heats are absorbed by flexible pavement and are accumulated in asphalt surface course, and this just makes pavement temperature be higher than temperature far away.Owing to the thermoplastic characteristics of bituminous material itself, easy deliquescing generation plasticity flows when high temperature simultaneously.Therefore China is most of regional, the sweltering heat in summer, and high-temperature duration is long, and in addition in the last few years, the traffic volume increases rapidly, vehicle maximizes, the serious channelization etc. that reaches that overloads, and makes flexible pavement be faced with acid test.The needs that just can not adapt to traffic are soon built up on many road surfaces, and early damage happens occasionally, and rut has become high temperature season flexible pavement the most serious potential mode of failure.
At problems such as asphalt pavement rut diseases, Chinese scholars has been carried out a lot of researchs, has proposed a lot of solutions.Adopt at present extensively modified bitumen, enlarge modified bitumen the scope of application (as surface layer bilayer modification in adopting), improve the composition structure (as the SMA road surface) of bituminous mixture etc.These measures have been played certain effect for the prevention or the alleviation of asphalt pavement rut.Yet because bituminous material is to responsive to temperature intrinsic propesties, abovementioned technology still fails to solve flexible pavement high temperature rut problem at all, special occasions such as high grade pavement especially big at the traffic volume, that traffic load is heavy and steel bridge face, abrupt slope bend, charge station, parking lot, the thermostability disease of flexible pavement is still serious.
Three, summary of the invention
The purpose of this utility model is: by showing reflectivity in brushing of plain asphalt concrete surface layer or spraying photothermal reflectance type coating to improve the road, thereby reduce the amount of heat absorption on road surface, reduce pavement temperature, reduce the rut disease, and gather materials and increase pavement skid resistance, thereby make this road surface become the photothermal reflectance type asphalt pavement structure of a kind of high antiskid, high anti-rut, good endurance by adding antiskid.
The technical scheme that the utility model purpose is taked is as follows: comprise supercrust and photothermal reflectance type coating, it is in the brushing of supercrust upper surface or be coated with photothermal reflectance type coating, in photothermal reflectance type coating upper surface spreading antiskid aggregate lift.
The utility model, described supercrust can be newly-built asphalt concrete pavements, also can be the old asphalt concrete road surfaces; Bituminous concrete can be the concrete structure of different grading types, as close-graded road surface, macrovoid drainage road.
The utility model, photothermal reflectance type coating is mixed together at normal temperatures by materials such as matrix resin material, high heat reflection fillers.
Antiskid aggregate lift of the present utility model adopts materials such as haydite, carborundum.
The utility model can be in existing existing asphalt concrete pavement or newly-built asphalt concrete pavement external coating or spraying, reduce the road surface caloric receptivity, reduce pavement temperature by increasing road table reflectivity, reduce the rut disease, have significant social and economic benefit, this pavement construction is easy simultaneously, curing time, is short, in time open to traffic.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing
Accompanying drawing is the utility model road structure schematic cross-sectional view.
Among the figure: 1-supercrust 2-photothermal reflectance type coating 3-antiskid aggregate lift
Five, the specific embodiment
As shown in drawings, adopt materials such as matrix resin, high heat reflection filler to mix stirring at normal temperatures, be prepared into photothermal reflectance section bar material, through the brushing or be sprayed on build or newly-built concrete pavement layer 1 upper epidermis on, form photothermal reflectance type coating 2, in photothermal reflectance type coating 2 upper surface spreading antiskid aggregate lift 3, obtain photothermal reflectance type asphalt concrete pavement structure by the short time health.
