REFLECTION CRACKING PREVENTION ELASTIC BITUMEN POLYMER WATERPROOF SHEETS FOR WATERPROOFING ASPHALT ROAD CONSTRUCTION

摘要

The present invention relates to an elastic waterproof sheet to prevent reflection cracking of a bitumen polymer for the waterproof construction of a concrete structure and an asphalt road. The elastic waterproof sheet improves durability through tensile strength higher than 40,000 N/m in a vertical direction and 24,000 N/m in a horizontal direction based on ISO 4603 by impregnating a Bitumen polymer. Additionally, the elastic waterproof sheet prevents water leakage by maximizing the adhesive strength at a superposed portion between sheets and between concrete and asphalt. The sheet can powerfully suppress water penetration into an upper plate of a bridge, and moreover, can remarkably improve durability with powerful adhesive strength.
