  • This study discusses the development of asphalt based waterproofing sheet applied on the blind side of the concrete substrate. The inorganic coating membrane is applied on top of the waterproofing sheet surface for protection, and adhesive bond to the concrete substrate surface is secured via hydration reaction the cement. The study reveals the experimental results of the overlap section tensile strength to observe the effects of the adhesion strength of this material.

  • In this study, to overcome the limitation of material application as the surface layer of bridge decks (asphalt concrete, concrete), a newly developed waterproof sheet is proposed to be usable for both asphalt concrete and concrete. Subsequent tensile bond strength was tested, and the test results showed that the tensile bond strengths were similar to depending on the type of the surface layer material for bridge decks, confirming the applicability of the proposed material.
