Bituminous expansion joint for watertight seals - comprising a rubber core covered with felt and sealed with impregnated bituminous compsn.

摘要: Bituminous expansion joint for water-tight seals of bitumen, asphalt, etc. suitable use in building comprises a central reinforcing bar rubber, onto both surfaces which are attached felts non-woven fibres and two outer bituminous layers cover penetrate the felt to reach core bar. Specifically, is EPDM (ethylene, propylene, diene, monomer), polyester fibre polymeric bitumen. The can easily be formed includes reinforcement. It resistant fatigue penetration by e.g. gravel. guaranteed long periods.
