Abstract
The invention discloses a noise-reduction wear-resistant bituminous concrete capable of reducing road noise and providing road surface with wear resistance.
Description
Technical field
The present invention relates to a kind of wear-resisting bituminous concrete of noise reduction.
Background technology
In recent years, developing rapidly with China Higher level highway construction scale, speed is being improved, and vehicle flowrate is also increasing
Plus, the influence of traffic noise becomes increasingly conspicuous.Noise causes public hazards to subjective reflection, or even is developed into extensive society and asks
Topic, reducing Noise Generated by Running Vehicles has turned into one of main path for curbing environmental pollution, therefore, open gradation concrete dynamic modulus pitch coagulation
Soil arises at the historic moment.According to research reports, open gradation Porous Asphalt Concrete road surface reduces than dense-graded asphalt concrete road surface and makes an uproar
4~6dB of sound.But, this open gradation Porous Asphalt Concrete road surface as superficial layer, exposed to natural environment and friendship
In gating condition, the influence of the factors such as sunshine, water, temperature change, traffic load is received throughout the year, and because its voidage is high
Up to more than 20%, pavement structure inside greatly increases with natural environment contact area, and water forms network flowing in space, ultraviolet
Line effect is more strong, exacerbate aging phenomenon, the serious curtailment service life on road surface.Although bituminous paving has wearability
It is good, be difficult dust, it is anti-skidding, waterproof the advantages of, but, because pitch is oxidizable in itself, easy to wear, easy high-temperature fusion and low
The characteristic of warm embrittlement, causes bituminous paving after using several years, and it washes away by surface oxidation, wheel friction loss, sleet, height
The factors such as temperature is dissolved, low-temperature embrittleness, cause road surface fine aggregate to be lost, surface pitch integument consumption is lost, coarse aggregate exposes, polishes
Phenomenon generally occurs, and road surface coefficient of friction is seriously reduced, and influences traffic safety, can also increase wheel and be rolled with road surface when contacting
The sound echo that air compression friction is produced increases driving noise；It is fatigability or road that seriously, therefore road surface occurs
Base reflex to road surface reflectivity cracking, make the swift increase of seepage of water on road surface, rainwater after crackle is seeped into asphalt road inside,
Internal stress hydraulic pressure is produced through the pressurization of road surface load, accelerates cracking for whole road surface, formed delamination and cause pit-hole, produce large area
The serious harm such as rupture, cave in.Therefore in order to extend the service life of bituminous highway, bridge, people must be in pavement usage one
The section time（General 2 ~ 3 years）Afterwards, repaired in time and maintained.It is aging and slight damaged that prior art solves bituminous paving
Method, is to be heated pour into a mould, irrigate, paving with asphalt field, and this method is not only seriously polluted, difficulty of construction big, due also to drip
It is blue or green cool down in atmosphere after fast thickening solidification, it is impossible to penetrate into the minute crack of cracking, do not have squeegee, cementation.And adopt
Sprayed with common emulsified asphalt, flood irrigation is repaired, though easy construction, flood irrigation effect are good, because emulsified asphalt molten point is low, with
Temperature raises its adhesive rate and declines to a great extent, and loses the cementation of fissures, bond effect, especially when summer high-temperature, usually because of the emulsification on road surface
Pitch is constantly walked after dissolving by wheel adhesive tape, and causes repairing work failure.
