Description
Technical field
The invention belongs to the technical field of compositions of asphalt material, and in particular at a kind of polymer emulsified asphalt ultrathin table
Sealing material and its preparation method and application.
Background technique
Ended for the end of the year 2016, highway in China total kilometrage up to 469.63 ten thousand kilometers, highway maintenance mileage up to 459.00 ten thousand kilometers,
Account for the 97.7% of total mileage of highway, wherein highway mileage open to traffic is more than 120,000 kilometers, is ranked the first in the world, huge highway is total
Mileage determines the great market demand of maintenance industry.
Highway in China is open to traffic total kilometrage cumulative year after year, realizes from " preliminary connection " to the great leap of " covering networking ".
However, along with the volume of traffic, load capacity and the further severe natural environment, climatic factor that increasingly increase, original asphalt road
Face has just occurred the road surfaces such as crack, track, pit slot, depression, surface fracture, loose early stage disease in not up to design period
Evil, this largely reduces the driving comfort level of bituminous pavement, and is unfavorable for traffic safety.For bituminous pavement morning
Phase disease, the road surfaces such as sealing, crushed stone sealing, micro-surface area, slurry seal, thin overlay sealing covers comply with social development demand,
At once it gives birth to.
Although the sealing covers such as crushed stone sealing, micro-surface area, slurry seal and thin overlay can the progress of road pavement early disease
Maintenance, maintenance, but equipment, construction technology, technical personnel quality are required more harsh.Meanwhile above-mentioned technology can also bring ring
Guarantor, energy waste, draws traffic road upper thread at waste disposal again, traffic and Socie-economic loss etc. one caused by overlong time of closing a road to traffic
Series of problems.
It is to be formed with polymer modification emulsified asphalt and polymeric additive water-based material as main component at ultra-thin table
Mixture.Using sealing high pressure sprinkling wagon, sprinkling forms superthin layer on bituminous pavement, can effectively close pavement microcrack,
It prevents to seep under moisture, improves waterproof performance, additionally it is possible to delay pavement asphalt aging, reduce asphalt surface course temperature, keep road surface anti-
Slip energy prevents road surface aging, improves road table friable state.
However, at the current ultra-thin table in China sealing material generally use common emulsified asphalt, SBR modified emulsifying asphalt or
The material to be formed is blended with water-base epoxy for SBS modified emulsifying asphalt, and since thickness is larger, moisture is difficult to volatilize, cementitious matter and base
Face adhesion strength is low, and wearability and skid resistance performance are bad, it is difficult to which meeting China, asphalt pavement of highway is preventative at this stage
Curing requirements.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of sealing material, the wearability and skid resistance performance of the material
