Product Design and T-joint Overlap Performance Research of a Double Carrier Reinforced Elastomer Modified Bitumen Waterproofing Membrane
A double carrier reinforced elastomer modified bitumen waterproofing membrane is introduced in this article,which uses SBS as a modifier and combines with high-quality polyester carrier to form a 7-layer structure.To solve the problem of excessive thickness of the membrane caused by the double carrier design,this product introduces ultra-thin carrier,enhances the adhesion of the overlapping edge,and increases the designed consumption of modified bituminous compound.Research has shown that in T-shaped overlapping areas,the bonding performance of the overlapping area can be significantly improved through separate hot melt construction and the use of asphalt coating for detail reinforcement,thereby enhancing the reliability of the waterproofing system.
