Every rain and snow, wet snow on the road traffic safety caused great risks; hot summer season, a large number of light adsorption heat hardening road, pedestrians walking in baked "geothermal carpet" on the miserable; traditional construction process results in pavement The initial level is low, the adhesion between the asphalt surface layer can not be formed interlocking, resulting in a discontinuous layer between the road leading to phenomena such as breakable and shorten life.
Civil Engineering and Architecture University, Beijing Jiaotong University Teachers cable-Based on the above issues, from the perspective of humanistic care, led the research team conducted research on the multi-purpose pavement material.
Final team developed: "through the snow," snow removal is a good helper, "clear cool" surface temperature change, a "healing music" road band-aid, "anti-haze treasure" automatic air purifier. In the heat of roads, choose low-cost, good effect of heat-absorbing water as the temperature phase change material, independent research and development into active modifier adsorbed water retention, the use of water heating characteristic slow to absorb heat generated by the road.
Cable-Chi, the "road surface temperature in the process of development but also with 'sponge cities' construction combined with the road surface by changing the level, increasing the proportion of coarse aggregate to increase the porosity of the surface to accelerate the realization of convection cooling at the same time better collection of surface runoff, infiltration purification supplement urban groundwater resources, which will further ease urban waterlogging and subsidence problems.
