Since the glued seam pressure with how to choose

Since the glued seam pressure belt adhesive seam pressure belt ( The road band-aid) In the repair of asphalt pavement is very convenient, so according to different situation, what should we choose different models? Material selection of vertical and horizontal cracks materials should be chosen with strong cohesive force, to adapt to the original pavement road surface shrinkage, insoluble in water, no water seepage, heat flow, low temperature embrittlement resistance and aging resistance of materials, commonly used pressure seam tape material with neoprene, emulsified asphalt, modified asphalt, asphalt rubber non-woven fabrics, etc. , considering the simple and convenient construction, economic and reasonable, choose building technology co. , LTD factory adhesive pressure belt of asphalt pavement, it is made of the modified asphalt non-woven fabrics. 2, test observation effect 2. 1 the effect of crack width on the material: will paste adhesive seam pressure zone construction when the crack width is bounded in 3 mm, greater than 3 mm and less than or equal to 3 mm paste with cracks respectively, paste for testing, after testing, respectively to adapt to the pavement temperature shrinkage effects on pressure belt. 2. 2: the influence of temperature to paste adhesive seam pressure zone construction of different temperature, respectively, records, after a period of time after the vehicle running, the seam pressure with the change of temperature in construction in different cases, the observation surface of bonding road detection. 2. 3: asphalt pavement water seepage test pressure seam through the water penetration test instrument in post fracture take water penetration test, through the test results, to detect the seam pressure coefficient of water seepage of take place whether meet the specification requirements. Since the glued seam pressure belt model is being selected, should understand the construction environment, according to the specific conditions of different, to choose the most suitable varieties, do the wasted effort effect.
