How is single ply modified bitumen applied in asphalt or bitumen modification processes?

Single ply modified bitumen is typically applied using a torch-down or self-adhesive method. In the torch-down process, a propane torch heats the underside of the membrane, allowing it to adhere to the substrate as it melts. Alternatively, self-adhesive membranes have a sticky backing that bonds directly to the surface upon pressure application. Both methods ensure a durable, waterproof seal, making them suitable for roofing and waterproofing applications in asphalt or bitumen modification processes.
