On July 25th, a new type of asphalt road bridge deck reclaimed maintenance coating was successfully developed and put into mass production in a chemical building material company in Qingdao. Due to the soaring traffic volume, coupled with a number of reasons such as design and construction and climate, many asphalt pavements have experienced microcracking, looseness, and other diseases in the early stages of their use. If they are not dealt with in a timely manner, microcracks will be caused by driving loads and road surfaces. The growth and widening under the effect of water seepage lead to the development of network cracks, block cracks and even pits on the road surface. In response to the various damage phenomena of the above asphalt pavement, Qingdao Runbang company's researchers lasted for 3 years, after repeated trials and demonstrations to develop a new type of asphalt pavement regeneration and maintenance of new materials JBS-C environmental protection asphalt road deck maintenance coating.

The material is mainly modified and emulsified by high-quality petroleum asphalt plus SBS and EPS, and added with heavy oil, high carbon, and polymer latex to perform coupling reaction to form a water-in-oil type non-polluting base emulsion, and then add inorganic materials. Silica-silver wear-resistant materials and elastic wear-resistance pellets are mixed. The product not only has the waterproof function of penetrating the repair of micro cracks, but also has the functions of improving the grinding resistance of the road surface, the temperature of the bridge surface, the noise reduction of the snow melting, and the comfortable driving.

After being sprayed on the road surface, it can quickly penetrate into the micro cracks on the road surface and recharge the asphalt binder material that the asphalt will fall off due to aging. The exposed aggregate will be re-wrapped and bonded, and the surface will be automatically bridged to a depth of 3 mm within a depth of 10 mm. The following micro-cracks, materials, materials can strengthen the adhesive force of asphalt loose material, and form an irregular spatial network structure on the road surface layer. This network structure can effectively prevent or suppress the further loosening of aggregates and the spread of micro cracks. Effectively prevent the erosion of rain or fuel on the road surface and play a role in waterproof and anti-aging. This mesh structure enhances the stability of the asphalt pavement surface.
