Description
Technical field
The invention belongs to technical field of road engineering materials, be specifically related to the little table of a kind of bituminous pavement place asphalt and preparation method thereof.
Background technology
Along with the develop rapidly of national economy, motorway mileage rapid growth.But the highway that build up early stage enters the big or middle after date of repairing, and has every year a large amount of bituminous pavements to overhaul, and the discarded amount of old pitch rapidly increases.
At present, China is " waste and old usefulness is new " to the overhaul of bituminous pavement basically, namely excludes old asphalt pavement and overlays new bituminous pavement.According to calculating of poor quality, the asphalt that China is discarded every year will surpass 2,000,000 tons, about 100,000 tons of its Asphalt Contents, and also along with the year by year increase of mileages of transport route, the pitch of being discarded and building stones will be multiplied.
Bitumen for road use mainly is petroleum pitch, but oil belongs to Nonrenewable resources, and excessive exploitation causes the exhaustion of resource at last.Like this, " one abandons one builds " to the overhaul of old road, has expended a large amount of resources, has increased construction costs.The used building stones of bituminous pavement are generally rolling the forming of rock of high-quality, and the effective regeneration utilization of building stones not only can be saved a large amount of rocks, can reduce destruction and attenuating environmental to the Nature simultaneously.If discarded bituminous concrete can not get effective utilization, it is stacked to process and also can bring expense, and causes the pollution of environment and the significant wastage of resource, is unfavorable for green circulatory and the Sustainable development of highway communication industry.
Summary of the invention
The purpose of this invention is to provide the little table of a kind of bituminous pavement place with asphalt and preparation method thereof, utilize the regeneration building stones in the waste asphalt mixture to prepare the asphalt that meets the little table of bituminous pavement place usefulness.
In order to achieve the above object, the present invention is achieved by the following technical solutions.
(1) the little table of a kind of bituminous pavement place asphalt is characterized in that, comprises following parts by weight of component: the cement of 100 parts regeneration building stones, the modified emulsifying asphalt of 7-9 part, 1-2 part, the water of 7-12 part.
Described regeneration building stones are the waste asphalt pavement material gained after peeling off, sieve, cleaning with milling.
Preferably, the little table of bituminous pavement place with the parts by weight of component of asphalt is: 100 parts regeneration building stones, 7.5 parts modified emulsifying asphalt, 1.2 parts cement, 8 parts water.
Preferably, in described 100 parts of regeneration building stones, particle diameter is regeneration building stones 10-30 part of 4.75mm-9.5mm, and particle diameter is regeneration building stones 40-60 part of 2.36mm-4.75mm, and particle diameter is regeneration building stones 10-30 part of 0-2.36mm; More preferably, in described 100 parts of regeneration building stones, particle diameter is 25 parts of the regeneration building stones of 4.75mm-9.5mm, and particle diameter is 55 parts of the regeneration building stones of 2.36mm-4.75mm, and particle diameter is 20 parts of the regeneration building stones of 0-2.36mm.
Preferably, described modified emulsifying asphalt refers to a modifying asphalt heating and melting, under mechanical agitation power, is scattered in the aqueous solution that contains emulsifying agent and auxiliary agent with fine particles, generates oil-in-water or water in oil liquid bitumen.
Preferably, described modified emulsifying asphalt is the SBS modified emulsifying asphalt.
(2) preparation method of compound of the little table of above-mentioned bituminous pavement place may further comprise the steps: each component of weighing, will regenerate building stones and cement are put into to be mixed in the pot, adds entry and stirs, and adds modified emulsifying asphalt again and stirs, and get final product.
The little table of bituminous pavement of the present invention place asphalt, have the following advantages: (1) has recycled building stones in the waste asphalt pavement material in large quantities, not only a large amount of rocks can be saved, destruction and attenuating environmental to the Nature can be reduced simultaneously.(2) the regeneration building stones have wrapped waste asphalt in advance, its surface property is better than new building stones, especially the waste asphalt that its surface wraps in advance after the building stones of the regenerating heating is more even, be beneficial to emulsified bitumen and regeneration building stones in construction mix and stir and pavement spread after combination, " standard specification for construction and acceptance of highway asphalt pavement " (JTGF40-2004) requirement that is content with very little of its pavement performance.(3) the regeneration building stones have wrapped waste asphalt in advance, can reduce Asphalt emulsion content 2%-4%, save cost.
