Design of Waterproof System for Cement Concrete Bridge Deck Pavement Based on Layer Functional Requirements

Currently, there is no unified standard for the design and testing of bridge deck waterproofing systems in China. In the application of waterproofing systems, there are many types of materials to be selected, and the selection of schemes is blind, with varying quality inspection and control standards. Therefore, a unified evaluation system should be determined based on the characteristics of each waterproofing material, combined with usage conditions and construction, to select suitable waterproofing materials, and to optimize the bridge deck waterproofing system based on the AHP analytic hierarchy process. By analyzing the various factors and related indicators that affect the bridge deck pavement waterproof system, a multi-level and multi-index evaluation structure model is established. Relevant experts in the field are used to score the multi-level indicators and evaluate the importance of each indicator. Then, a judgment matrix of each level of indicators is constructed by using the analysis method promoted layer by layer by AHP to calculate its importance and conduct consistency test. Finally determine the importance of each program, to achieve quantitative selection of more reasonable programs.
