Description
Technical field
The present invention relates to a kind of colorful asphalt emulsion and preparation method thereof.
The invention still further relates to the application of colorful asphalt emulsion at colorful slurry sealing layer.
Background technology
Colorful slurry sealing layer is with several kinds of starting material such as the aggregate of suitable grating, filler, emulsified bitumen, water, additive and special coloring agents, mixes by a certain percentage to join and mixes and stirs, and processes uniform slurry mixture, and thickness on request and width pave on the road surface.No matter the colorful slurry sealing layer construction is to inferior grade road or advanced road, no matter is to urban road or view road, can produce remarkable economic efficiency and social benefit.Colorful slurry sealing layer can make wearing and tearing, aging, crack, disease such as smooth, loose; Obtain rapidly repairing; Play waterproof, effect such as anti-skidding, smooth, wear-resisting, and colorful slurry sealing layer on the view road, to have construction costs low, characteristics such as constructional method simple and fast.
The color emulsified asphalt Construction Technique for Slurry Seal Coat still is a new technology in China, is mainly used in the following aspects at present:
1, the maintenance of old asphalt pavement
Bituminous pavement since long-term exposure under physical environment, receive Exposure to Sunlight, wind, drench with rain and the effect of freeze thawing the repeated load effect that also will bear vehicle simultaneously.After the use of road surface through one period, fatigue can occur, the road surface can present phenomenons such as cracking, loose, aging and wearing and tearing.Like untimely maintenance process, damaged road surface receives the erosion of surface water, will make the soft bullet of basic unit, and the bulk strength on road surface descends, and causes the destruction on road surface.If bituminous pavement is just taked necessary precaution property maintenance measure---emulsified asphalt slurry seal before not destroying; Old pavement is taken on an entirely new look; And make road surface after the maintenance have waterproof, antiskid, characteristics such as wear-resisting; Be a kind of good resist, played the effect that prolongs service life of road surface.
2, the shop wearing course on the sand-gravel surface
Making emulsified asphalt slurry seal on the sand-gravel surface after the smooth compacting can make the sand-gravel surface outward appearance have the characteristic of bituminous pavement, improves the abrasion resisting performance of sand-gravel surface, prevents airborne dust, improves driving condition.In county, the transformation of township level rural highway, have wide practical use.
3, the maintenance of cement concrete pavement and bridge floor
Emulsified asphalt slurry seal has good tack to cement concrete; After cement concrete pavement is because of driving for many years; The road surface produces crack, pitted skin or slightly not at ordinary times, adopt emulsified asphalt slurry seal after, can improve the outward appearance on road surface; Improve the planeness on road surface, prolong the work-ing life of cement concrete pavement.Service diagram surface layer at bridge adopts the emulsified asphalt slurry seal punishment can play the cover effect, and seldom increases the deadweight of bridge floor.
1, the laying on view road
For the view property road at scenic spot, mainly be sightseeing property road, it is not very high that traffic loading is required, and adopts traditional road construction method, not only the cost cost is high, and long construction period.As adopt colorful slurry sealing layer to lay, not only can greatly practice thrift construction cost, and quick construction is convenient.
Summary of the invention
