Pavement self-adhesive seam tape

, Structural characteristics paste rolled seam tape is a type of crack resistance waterproofing membrane, which is made of 2mm thick waterproof polymer film coated on the anti-wrinkle 0.3mm thick heavy-duty polypropylene material, through strict process rolling complex in Together, the removal process to prevent adhesion of silicone-coated paper with a waterproof membrane isolated from the outside, so the products there are three layers of material. Paste slit width of the tape, 8 cm, 12 cm, 15 cm, three specifications, according to the slit width and crack need to cut or splice site, it can also be customized using the unit. Second, the use of performance: As the causes of cracks in the road surface, shape, degree is very complex, with a surface layer affixed to sew a variety of specifications to meet on-site use, divided into wide slit (in transverse joint based), slit (portrait based) and split three networks, primarily reflecting wide slit crack, the general use of the width of 15 cm surface layer of paste seam zone, due to cracks wider, it should first be pouring and laying; slit mostly asphalt mixture construction joints, narrow width, and can be laid directly width of 8 cm of the surface layer of paste seam tape, the network split (including cracks and other irregular cracks) To cause analysis, below the asphalt surface layer itself can be directly caused by cracks 450mm wide use of surface paste with stitching seam laying. Performance parameters Model seam tape affixed to the surface layer thickness (mm) 2.0 / 2.5 Heat resistance ℃ 85 without sliding, flowing, dripping Rally, N / 50mm≥ No low temperature flexibility, ℃ -30 4.0 or shear viscosity and surface properties external fault puncture resistance impermeable rupture strength, N≥ 200 artificial climate accelerated aging appearance of a non-sliding, flowing, dripping pull retention rate,% ≥ 90 low temperature flexibility, ℃ -25
