Description

A kind of water-based road bitumen analeptic and preparation method thereof
Technical field
The present invention relates to a kind ofly beautify and repair early diseases such as bituminous pavement is aging, pitted skin, minute crack, infiltration; Ability rapid permeability bituminous pavement top layer; Airtight road surface, administer pitted skin, hold loosely, make minute crack up, reach water shutoff; Road bitumen analeptic of road improvement anti-slide performance and graceful road surface outward appearance and preparation method thereof belongs to bituminous pavement maintenance and repair association area.
Background technology
Along with bituminous pavement more and more widely is applied in motorway and the urban road construction; The common diseases of bituminous pavement such as the road surface is aging, crack, pitted skin, loose, sandization, damage by water are bad are influence normal use of road and the maximum killer of reduction of service life; Carry out the comprehensive regulation as untimely, can quicken road and damage, strengthen the road maintenance cost; Influence road and normally run, cause heavy economic losses.This moment, the road surface did not structurally have big damage, and is little to the influence of driving.Generally in this case, the road surface composite quality index is more than very reaching very, and pavement condition index PCI is between 80~95.Be the best moment that road pavement is carried out preventive maintenance at this moment.
Characteristics such as preventive maintenance has that easy construction, construction time are short, social benefit and economic benefit are good.The preventive maintenance method is a lot, like mist seal, little table place, slurry seal and thin overlay etc.This a series of technology has obtained using widely in the U.S., Canada and some European countries, and has obtained tremendous economic and social benefit.External experience shows, road is taked planned maintenance measure, improves pavement durability, can effectively prolong highway work-ing life, improves the economical, societal benefits of road efficiency of operation and performance road itself.To road early investment 1 yuan, can save the input of later stage 6-10 unit.Yet in the applying at home, technology such as little table place, slurry seal and thin overlay is relatively stricter to equipment, construction technology, technician's quality.Simultaneously, after adopting these technical finesses, also can bring environmental protection, waste disposal, energy dissipation, heavily spread a series of problems such as traffic road surface white line, traffic that the road closure overlong time causes and socioeconomic loss.Both at home and abroad environmental protection, high performance preventive maintenance material are begun one's study at present and use.The Pavement Dressing Conditioner of U.S.'s development (is called for short PDC; U.S. Patent number 5; 580,603) be a kind of preventative asphalt pavement regeneration agent, yet this material not too obvious to the effect of diseases such as handling crack, the ageing of asphalt occurred 3~5mm and come off, serious loose.Domestic development and the application that has also begun said material, but do not see application report.
In recent years, along with the appearance of national relevant policies, traffic departments at different levels very pay attention to the preventive maintenance of road, and road preventive maintenance market enlarges gradually.Domestic nearly 20% bituminous pavement is in the precuring stage.It is predicted, about 30,000 tons/year in nearest 1~2 year market to the demand of such conserving material, the Market Growth phase in 3~5 years, market can reach 5~100,000 tons/year to the demand of said material.Expectation is about 10 years, and the market requirement total amount of this project will be about 300,000 tons/year, and market capitalisation reaches 12,000,000,000 yuan.
Along with domestic environmental protection heats up gradually; And society and the masses are increasingly high to the demand of highway communication, high-grade highway and urban road preventive maintenance market to adhesion property, the endurance quality of preventive maintenance material, beautify function such as redeck and proposed requirements at the higher level.Yet be that the low-grade bituminous pavement preventive maintenance material of representative still accounts for larger proportion with emulsified bitumen, modified emulsifying asphalt on the home market, and high-performance, environmentally-friendly asphalt analeptic material are in blank.
Summary of the invention
The present invention is according to the existing deficiency of pre existing conserving material on asphalt roads maintenance environmentally friendly Development Trend of court and the market; Purpose is to provide a kind of water-based road bitumen analeptic and preparation method thereof; Be used to beautify the road surface outward appearance, improve road anti-slide performance and water resistance, solve bituminous pavement early diseases such as ageing of asphalt, loose, pitted skin, fine cracks, infiltration; And prevention or check disease development and spread, thereby prolong road life.
The object of the invention is realized through following technical scheme:
A kind of water-based road bitumen analeptic is characterized in that by weight percentage it is made up of following component: pitch 20 ~ 30%; Water 10 ~ 20%, solvent 5 ~ 10%, properties-correcting agent 10 ~ 20%; Emulsifying agent 0.5 ~ 2%, adhesion promoter 0.5 ~ 1%, anti-settling agent 0.5 ~ 2% and filler 25 ~ 40%.
