Description
Technical field
The invention belongs to asphalt pavement technique field, relate to a kind of heat-reflective color emulsified asphalt and compound thereof.
Background technology
Asphalt, as a kind of heat-sink material, reaches 0.85 ~ 0.95 to sunlight heat specific absorption, and the high-absorbility of bituminous pavement to sunlight causes asphalt pavement warm to spend high major cause.Due to China's most area, the highest temperature in summer can reach 35 DEG C ~ 40 DEG C, and under sunlight prolonged exposure, amount of heat is absorbed by bituminous pavement and accumulates in bituminous pavement, the temperature of bituminous pavement can reach 63 DEG C ~ 68 DEG C, and makes bituminous pavement produce rut.High temperature is the most direct inducement that rut produces: high temperature makes the rheological property of pitch transform from visco-elasticity to plasticity, and stiffness modulus declines to a great extent, and its non-deformability sharply reduces, under the effect of vehicular load, just occur serious rut.Current pavement material circle extensively adopts modifying asphalt, uses high-quality to gather materials, adopts extruded aggregate grating, adds the high-temperature behavior that the measures such as anti-rut agent improve bituminous pavement, but due to the thermally sensitive intrinsic propesties of bituminous material, these measures fundamentally do not solve bituminous pavement high temperature rut problem yet.
Meanwhile, China's urban road mats formation form mainly based on bituminous pavement, and the amount of heat of bituminous pavement accumulation seriously exacerbates " tropical island effect " in city.And the current general measure solving city " tropical island effect " improves urban forest cover rate and expands meadow, water ground area, to change the state of city underlying surface, but city is a region that building height is intensive, road height is densely covered, the forest coverage in city etc. are extremely difficult to be improved.
And China's pavement of road mostly is grey or black, grey and the neural system of black to people have calm effect, but watching dull grey road surface for a long time attentively can make driver attention slow up, bring out fatigue, even drowsy, the danger of generation traffic accident is increased.
Therefore, for Bituminous Pavement Wheel Rut Question, " tropical island effect " in city and the single dull problem of pavement of road color, be necessary that exploitation one possesses heat reflectivity, the caloric receptivity of bituminous pavement can be reduced, greatly reduce bituminous pavement temperature, reduce asphalt pavement rut disease, alleviate city " tropical island effect ", aesthetic road view, improve the high-molecular compounded and modified color asphalt of heat-reflective of traffic safety, itself and certain graded aggregate compound are made heat-reflective chromatic bitumen mixture to pave in road surface, play reflection, radiation solar heat, reduce bituminous pavement temperature, prevent asphalt pavement rut from injuring, reduce the effect of urban heat land effect to a certain extent simultaneously.
