Abstract
The invention discloses a construction method for asphalt road protection, which relates to the provision of a rapid construction method for water-proof, grease-proof and skid-proof asphalt road protection. The method comprises the following steps that: a, an asphalt synchronous chip sealer is used for spraying a layer of water-proof and grease-proof binding liquid material, and spreading a layer of anti-skid fine sand aggregate at the same time; b, according to the predetermined material consumption, the spread layer of fine sand can be completely covered and wetted sufficiently by a binding liquid; and c, after a period of time, part of the binding liquid material can penetrate into gaps and microcracks of an asphalt layer, the moisture or a solvent in the binding liquid is evaporated, the binding liquid is solidified and dried so as to seal leakage passages such as the gaps and the microcracks of the asphalt layer, and simultaneously, a thin film formed by the binding liquid after drying coats the spread fine sand and a layer of the fine sand is bonded and fixed on an asphalt surface coarse, so that the friction coefficient of the asphalt surface coarse is improved. The construction method synchronously sprays the binding liquid and spreads the fine sand through mechanical construction, which improves construction efficiency greatly, has long road section of continuous operation, has water-proof, grease-proof and skid-proof effects on the asphalt surface course, and fulfills the aim of protecting an asphalt road.
Description
Technical field
The present invention relates to the job practices of asphalt road protection.
Background technology
Asphalt roads is after bitumen layer is mated formation completion; Hazardous substances such as water and greasy dirt can enter into bitumen layer with (little) crack through the loose space of bitumen layer; Under effect of factors such as driving, variations in temperature, will cause the damage on bitumen layer road surface, cause shortening the application life of flexible pavement.
Existing asphalt road protection technology is on bitumen layer, directly to spray mulseal or chemical protective agent; Or overlay little table place and various skin coat; Though these protections have the waterproof and oilproof effect to bitumen layer; But the applicability of different process respectively has the restriction of some aspect, and is higher like non-skid property reduction or cost.
Summary of the invention
The object of the present invention is to provide the rapid constructing method of the anti-skidding asphalt road protection of a kind of waterproof and oilproof.
The object of the invention can be realized like this, designs a kind of job practices of asphalt road protection, may further comprise the steps:
A, use the binding liquid material (mulseal, reducing agent, coal tar, chemical glue etc.) of chip sealer spraying one layer waterproof and oilproof, spread the anti-skidding fine sand aggregate of layer overlay synchronously simultaneously, spill binding material again after also can spreading fine sand earlier;
B, according to predefined material usage, the layer of fine sand of spreading the shop can access the covering fully of binding liquid and fully soak profit;
C, through after a while, part binding liquid material will penetrate in the space fine fisssure of bitumen layer, moisture or solvent in the binding liquid evaporate; The curing of binding liquid is dry; To seal bitumen layer space fine fisssure isotonic water passage, simultaneously, the film that forms after the binding liquid drying firmly is wrapped in the fine sand that spreads the shop; And be bonded and fixed at layer of fine sand on the asphalt roofing, improve the friction factor of asphalt surface course.
The present invention sprays binding liquid synchronously and spreads the shop fine sand through mechanical execution, and efficiency of construction is greatly enhanced, and bitumen layer has waterproof and oilproof and skidproof effect, reaches the purpose of protection asphalt roads.
Description of drawings
Fig. 1 is a generalized section of the present invention
The specific embodiment
Below in conjunction with embodiment the present invention is done further description.
A kind of rapid constructing method of asphalt road protection may further comprise the steps:
A, use chip sealer even spraying one layer waterproof and oilproof binding liquid (mulseal, reducing agent, coal tar, chemical glue etc.) are evenly spread the anti-skidding fine sand aggregate of layer overlay simultaneously synchronously;
B, according to predefined material usage, after fine sand spread and is layered on the binding liquid, fine sand can access the covering fully of binding liquid and soak profit;
C, through after a while, the part binding liquid will penetrate in the space fine fisssure of bitumen layer, moisture in the binding liquid material or solvent produce evaporation; After the binding liquid material cured drying; Can seal bitumen layer space fine fisssure isotonic water passage, simultaneously, the film that forms after the binding liquid drying firmly is wrapped in the fine sand that spreads the shop; And be bonded and fixed at layer of fine sand on the asphalt roofing, improve the friction factor of asphalt surface course.
Plant equipment that the present invention adopted and material all can buy on market, and the main component of these materials is main with mulseal, pitch reducing agent, bitumen regenerant, coal tar, chemical glue and fine sand basically, and the title of commodity is different because of producer.
Adopt asphalt road protection job practices of the present invention as shown in Figure 1; Binding liquid 2 is sprayed on the asphalt surface course 1; Penetrate in the space fine fisssure of asphalt surface course 1, solidify the space fine fisssure of rear enclosed asphalt surface course 1, reach the effect of asphalt surface course 1 complete waterproof and oilproof.When fine sand 3 spread be layered on 2 li of binding liquid after; Obtain the covering of binding liquid 2 materials and fully soak; Fine sand 3 fillings are squeezed and are embedded in the space fine fisssure of asphalt surface course 1, and spread the fine sand 3 of shop through the firm parcel of film that forms after binding liquid 2 drying of materials, are bonded and fixed at layer of fine sand 3 on the asphalt roofing 1; Improve the friction factor of asphalt surface course 1, reach anti-skidding effect.
Said chip sealer is the construction equipment commonly used of highway engineering construction; Can evenly carry out the shop of spreading of spilling cloth and fine sand 3 of binding liquid 2 simultaneously; Speed of application is fast; The highway section of working continuously is long, and the asphalt surface course 1 after the construction has waterproof and oilproof and anti-slip technology effect, and whole asphalt surface course 1 reaches uniform appearance.
Said binding liquid 2 materials contain moisture or solvent, spill cloth behind asphalt surface course 1, immediately asphalt surface course 1 are permeated and evaporate, and can seal the space fine fisssure of bitumen layer 1 after the curing, the infiltration of anti-sealing and oil.
Said fine sand 3 has hardness height, resistance to compression, squeezes embedding and antiskid function.
Said predefined material usage is to confirm different pitches surface layer 1 structure required binding liquid 2 and fine sand 3 consumptions through testing, and the binding liquid 2 of spilling cloth can fully cover soaks fine sand 3.
Said binding liquid 2 dry rear films firmly are wrapped in the fine sand 3 that spreads the shop, are bonded and fixed at layer of fine sand 3 on the asphalt roofing 1, improve the friction factor of asphalt surface course 1, reach anti-skidding effect.
