AI Technical Summary

Technical Problem

The existing root-resistant waterproof coils are made of long-fiber polyester tires as reinforcement layers, which hardens after long-term storage, resulting in cracking of the base layer, which poses a risk of water leakage and plant root penetration.

Method used

The cross-laminated film is laminated from top to bottom, a rubber modified asphalt layer with root puncture resistance and a non-cured rubber asphalt waterproof coating layer. The cross-laminated film is composited by a single-layer film cut obliquely 45°. The rubber modified asphalt layer is prepared by SBS and SBR rubber modified asphalt. The non-cured rubber asphalt waterproof coating layer has self-healing properties and can fill the gaps of the base layer by itself.
