Slurry seal is a road cover construction technology, whether it is cement or asphalt pavement road surface; whether it is parking, or urban roads; whether it is applicable to general highways or highways. In theory, new and old pavement can be used, but very few people in the world in the new road surface, but widely used in the old road maintenance, especially for the early road surface aging, cracks, loose, rutting, polishing and other diseases The use of slurry sealing technology, can quickly repair the road, to fill the rut, improve the road surface smoothness, water resistance and anti-skid. Slurry seal is characterized by prominent at room temperature, the construction site in the slurry mixture mixing and paving. Compared with the hot mix asphalt mixture cover, no heating and cooling, no rolling molding. Slurry sealing technology was invented in Germany around 1930, the twentieth century
60 years in Europe to promote and develop. 20 years ago, China began to contact slurry slurry technology, when faced with the English "Slurry seal coat" in Chinese, literally translated as "mortar seal" or "asphalt mortar seal. At that time, Mr. Jiang Yunhuan led the "cationic emulsified asphalt and road performance," the state key task force from the engineering situation, that the slurry sealant mixture is different from the building mortar, but also different from the general asphalt mortar, according to the technical characteristics of the Slurry seal coat explained as slurry seal, from the slurry seal the four words to become emulsified asphalt binder, at room temperature conditions, site mixing paving in situ pavement construction technology special term. "Slurry seal" the mixture of the traits, the role and the structure of the structure are summarized in the inside, very intuitive and easy to understand. These words have been recognized by everyone, has become China's irrevocable professional terms. 1970s, modified asphalt technology has made significant progress, along with modified asphalt emulsification technology has also made a major breakthrough, modified asphalt and modified asphalt to make the traditional oil asphalt performance has been greatly improved . Slurry sealing technology as a result of modified asphalt binder as emulsified, so that the thickness and performance of the seal layer has been greatly improved, coupled with the quality of the sealing material mixture, the ratio of more stringent requirements on the sealing layer Machine also made a larger improvement. As a result, in foreign reports appeared in the "Micro-Surfacing"
