Modified asphalt waterproofing membrane for road, bridge, high-speed railway and tunnel is a kind of polymer modified asphalt waterproofing membrane, which is made of polymer modified asphalt as coating layer, long-term polyester fiber felt as matrix and fine sand as coating material.
Modified asphalt waterproofing membrane specially used for road and bridge can withstand the rolling construction of hot asphalt concrete at high temperature. It has strong bonding strength with hot asphalt concrete and can transmit the horizontal moving load of heavy traffic. Modified asphalt waterproofing membrane used for road and bridge has great toughness, which can strengthen the backing of asphalt concrete. It can effectively prevent the occurrence and development of cracks in asphalt concrete, and improve the service life of asphalt concrete pavement and the comfort of vehicles. The strength, elongation and high and low temperature performance of modified asphalt waterproofing membrane for road and bridge are superior to those of ordinary self-adhesive, SBS and APP waterproofing membrane. It is absolutely impossible to use ordinary waterproofing membrane for road waterproofing construction.
