And the road surface has strong intensity, strong deforming ability, strong wearability, good antiskid property, water permeability, noise reduction, low manufacturing cost, etc.
Description
One, affiliated field
The present invention relates to the road surface structure technology, especially a kind of rolled polymer modified cement-concrete sprayed colour road surface structure and job practices.
Two, background technology
Colored road surface can play the effect of moving car alarm and beautifying city, and can play the visual fatigue of alleviating the driver to a certain extent, the effect that provides safe driving to ensure better.
(1) present colored road surface both domestic and external has following several:
1, colour concrete road surface:
Be on not dried cement floor, to add last layer colour concrete (ornamental concrete), on the cement floor, suppress forming then with special-purpose mould.Colour concrete can make the cement floor present various color and lusters, pattern, texture, the material and the texture of energy simulating nature, all kinds of patterns of cropping.
According to construction technology, the colour concrete road surface can be divided into following several again:
Pressing mold series (impression terrace) is meant when laying cast-in-situ concrete; adopt colored hardening agent, separating powder, protective agent to come the ornamental concrete surface, with the visual effect of the color of concrete surface and concavo-convex texture performance lithotome, bluestone board, granite even timber.
Paper matrix series refers to choose the paper matrix template pattern, is arranged on the cement face of new filling, sprays colored hardening agent to the zone of completing template, and evens out, behind the dry forming, pulls off template, and clean surface goes up protective agent then.
Spraying series is to adopt spraying method that sprayed on material is uniformly applied to cement surface, gloomy cement surface is become bright and clean, colour, the effect of special texture or pattern is arranged.Sprayed on material is epoxy resin or other macromolecular material.
Ground, metope, the sight spot of various material such as that colour concrete can be used for decorating is outdoor, indoor cement based: as square, sidewalk, track, parking lot, external wall etc.
2, color anti-skid road surface
Initiate in Europe on this road surface, and utilization is more in Europe.
Anti-skid surface: use special modified resin, comprise-(this resinae building stones are commonly called as " pottery " building stones, thickness 2 millimeter for the resin-based binding agent (epoxy resin or other macromolecular material) of special formulation and the aggregate of various different sizes.), evenly be coated on pitch, cement concrete pavement.
When resin and aggregate added dyestuff and make colour, this surface course promptly was called colored road surface.Because the surface layer on this kind road surface can make it abrasion performance and antiskid by technical measures, therefore be called " color anti-skid road surface " again.
3, color asphalt road surface
The binding material on color asphalt road surface is not pitch in fact, but resin (in add dyestuff), gather materials and be generally colour and gather materials (as red or green), resin heating becomes behind the plastic state and the uniform mixing of gathering materials, transport in-place forming to, after resin temperature reduced curing, surface layer formed, and is called the color asphalt road surface traditionally.(, make the modification technology of colored road surface of the pitch of black and fail far away to realize) in fact because the pitch true qualities are black
(2) characteristics on various road surfaces
According to the simple introduction of front, there is following shortcoming in existing colored road surface:
1. colour concrete road surface: because the colour concrete road surface forms by cement concrete surface is handled, so its skid resistance is relatively poor, is unsuitable for high speed traveling, has restricted the application of this kind road structure in high-grade highway and urban road; On the other hand, also usually there are some problems in finish materials and concrete bonding, processing layer is come off, thereby influence outward appearance; In addition, the durability of Facing material usually can not reach requirement, and application life is short.
2. color anti-skid road surface: form owing to overlay the antislip colour wearing layer at the flexible pavement top, therefore it cost an arm and a leg (asphalt surface course and special anti-skidding wearing layer price are all higher), construction technology complexity (flexible pavement of at first constructing), (anti-skidding wearing layer is thinner for the construction process requirement height, generally have only several millimeters, even for guaranteeing this layer thickness, all higher requirement can be arranged to the technology of former surface layer and overlay).
3. color asphalt road surface: resin as the color asphalt road surface price of binding material high-because the price of resin is the several times of pitch generally speaking, and its aggregate is the natural aggregate of special color, so the price of aggregate also is higher than general aggregate far away; Construction technology complexity-Re mixes and stirs, and technological process is identical with flexible pavement, but requirement is higher, because colored road surface needs more protections in construction, could guarantee that color is not contaminated.
In addition, loading angle from road structure, colour concrete road surface and color anti-skid road surface belong to a big class: stress characteristic-concrete road surface structure and asphalt pavement structure that they do not change original road surface are still stressed primary structure, so they have the shortcoming of the stressed aspect of former road structure.
Special needs to be pointed out is: above several colored road surfaces all do not have pervious function, noise pollution are not had obvious improvement yet.
