WJG-114 Modified Asphalt Waterproofing Membrane for Bridges
WJG-114 modified asphalt waterproof membrane for bridges uses polyester felt as the base material, thermoplastic elastomer (SBS), atactic polypropylene (APP), or polyolefin polymers (APAO, APO) as modifying materials. High-quality petroleum asphalt is modified and combined with plasticizers, reinforcing agents, etc. After being coated and rolled, the surface is covered with mineral flakes, fine sand, and a PE film to produce the waterproof membrane.
