bridge expansion joints bridge structure is the most vulnerable to damage and more difficult to repair the site, is one of the bridge construction and maintenance problems.
US ENNIS Group's specialized subsidiary of British PRISMO company (formerly Shell subsidiaries) BJ200 bridge expansion joint filler is an acquired several patents for highways and general road bridge expansion joints joint compound ( United Kingdom Patent No. 2001379B, European Patent No. 0000642) BJ200 seamless bridge expansion joint system is a high polymer modified asphalt BJ200 and selection of aggregate size "combination" is made, the product has the following characteristics: . 1 compatibility, good toughness: in asphalt and concrete pavement construction; meets the horizontal 50mm repeated temperature and load displacement, without complex mechanical devices. 2. The low temperature flexibility and high temperature stability are very good: when does not become brittle at -40 ℃, at 80 ℃ when not flow. Therefore, it can be applied to all climatic zones China. 3. Construction of convenient and flexible: can demi construction without obstructing traffic. 4. open traffic quickly: seamless joints bonding material after installation, for 1-2 hours in cold weather, hot weather 3-4 hours to open traffic. 5. easy to repair: If damage occurs, it is easy to fix. 6. reduce urban noise pollution: absorb vibration of the vehicle through the bridge joints, basically no noise. 7. comfort is very good: seamless joints bonding material can fully absorb the shock and vibration of the vehicle, the vehicle passing smooth and comfortable. 8. economic good: convenient construction, the required simple equipment, easy maintenance, low traffic pressure. Durable, maintenance replacement, good economic returns. Second, the current market conditions As far as we know now it entered the Chinese market in the seam material are the following situation: 1, from the United Kingdom PRISMO (case of the United States ENNIS's professional company) BJ200 bridge expansion joint material. Its products are historic and patented a high polymer modified asphalt. At present, widely used in China. 2, MATRIX502 reinforced asphalt seamless bridge expansion joint system from the United States CRAFCO company first entered China, the company's strengths is asphalt fog seal materials technology, is commonly known as the "Golden Bear oil." 3, from Korea Lobo HW-GTF and HW-TST enter China a few years ago, said the materials industry is an imitation of the product, since the material quality problems, has been withdrawn from the market.
