Polymer Modified Bitumen Membrane for Railways

Railway bridge contractors need heavy-duty roll material compliant with rail standards to withstand hot asphalt paving and long-term train loads. Our Polymer Modified Bitumen Membrane for Railways is railway-specialized solid Highway Coating base layer, an integral large-area component of complete Road Protection System, matched with auxiliary Traffic Sealant tapes to deliver reliable long-term Bridge Waterproofing for high-speed railway concrete bridge decks.   It adopts long-fiber polyester base and SBS modified bitumen covered with fine sand isolation layer, fully compliant with TB/T 2965-2018 railway deck standard. Unlike liquid polyurethane coating, this solid 4.5mm-thick roll comes in 1m–2.2m width, with customized length fitting simply supported beams of different spans. Its strong base adhesion prevents delamination and water seepage; high tensile elongation adapts to substrate deformation, while excellent high-temperature shear resistance fully resists hot aggregate compaction…
