Recently, a new type of asphalt road deck reclaimed maintenance coating was successfully developed and put into mass production in a chemical building materials company in Qingdao. For asphalt pavement prone to micro-cracks, loose, etc., Qingdao Runbang company's scientific staff lasted 3 years, after repeated trials and demonstrations to develop a new type of asphalt pavement regeneration and maintenance of new materials - JBS-C environment-friendly asphalt bridge deck maintenance coating.
The new materials are mainly modified and emulsified by high-quality petroleum asphalt plus SBS and EPS (extensible polystyrene), coupled with heavy oil, high carbon, and polymer latex to form a water-in-oil-type pollution-free reaction. The basic emulsion, and then added inorganic calcium silicate wear-resistant materials and elastic wear resistance particles mixed. The product not only has the waterproof function of penetrating the repair of micro cracks, but also has the effects of snow-reducing noise, comfortable driving and so on.
After the material is sprayed on the road surface, it can quickly penetrate into the micro cracks on the road surface, recharge the asphalt binder material that the pavement peels off due to the aging of the asphalt, re-wraps the exposed aggregate material, and automatically bridges 3 mm within a depth of 10 mm. Wide cracks below. The functional materials in the material can strengthen the adhesive force of the asphalt loose material and form an irregular spatial network structure on the road surface layer. This network structure can effectively prevent or curb the further loosening of aggregates and the spread of micro cracks, effectively preventing rain or fuel oil from eroding the road surface, and has a waterproof and anti-aging effect.
