ANALYSIS ON ADHESIVE PERFORMANCE OF WATERPROOFING LAYER IN CONCRETE DECK SLABS WITH CRACKS AND BENDING CONDITIONS

Abstract

In order to keep a waterproofing function, it is important for waterproofing layer to have good adhesion Performance to concrete deck slabs. However as concrete deck slabs accept on wheel load, an adhesion performance of waterproofing layer might be influenced by bending condition of deck slabs and crack on concrete deck surfaces. Therefore, by this study, adhesion performance of the waterproofing layer on concrete deck slabs with bending conditions were examined by using FEM analysis. And also the influence of cracks on concrete deck surfaces to adhesion performance of the waterproofing layer was investigated. As a result, it makes sure that the concrete deck slabs with bending condition influence on the growing stress of waterproofing layer, and also the large stress is occurred on the waterproofing layer of an end of crack of concrete deck surface.
