Crack sealing machine is specially used to sealing the crack and srevices in the pavement of express ways,highways,municipal streets and airports after new opening and heavy repaired.After notched by crack router and sealing by special sealing glue,ensure the whole usability and working time. However, it is necessary to choose sealant with high quality in order to make the best use on sealing crack, and road maintenance.
Crack is one of the major diseases of asphalt pavement, using a variety of techniques to close pavement crack closure to prevent penetration of water into the internal structure of the road, turned out to be the road to prevent water damage to slow the disease appears to extend the effective life of the pavement means, as domestic and foreign Asphalt Pavement Prevention Required program of conservation. Study pouring equipment and pouring material is also becoming more mature, and its representative products are high-performance hot melt asphalt pouring glue. High temperature stability of Europe and imported products have good ductility and low temperature cracking performance, but the price is higher, and the applicability of the region imported products in different countries are different. In order to meet the domestic demand for high performance asphalt road pouring plastic, for the current domestic problems of similar products, our research by analyzing the imported products, the performance of domestic products, independently developed the DR series pouring glue products. DR series pouring glue into four types: high-temperature, ordinary type, low temperature and cold type, respectively, for 0 ℃, -10 ℃, -20 ℃ and -30 ℃ regions.
