Materials and Performance of Asphalt-Based Waterproof Bonding Layers for Cement Concrete Bridge Decks: A Systematic Review

Abstract

As an important part of the bridge deck pavement system, the waterproof bonding layer plays a vital role in ensuring the integrity and durability of the pavement structure. Asphalt-based waterproof bonding materials have attracted extensive attention from researchers due to their low cost and good combination with asphalt surfaces. However, the existing research results of asphalt waterproof bonding layers are confused and there is a lack of systematic summaries. In addition, there are significant differences in the type, specification, performance, evaluation method, and evaluation index of asphalt materials. The performance evaluation indexes and methods of asphalt waterproof bonding materials need to be further studied and improved. To further promote the research and development of asphalt waterproof bonding layer materials, in this paper, the relevant specifications for the waterproof bonding layer of roads and bridges in China were systematically combed, the key performance index requirements in different specifications were compared and evaluated, the research trends of the asphalt waterproof bonding layer in China and its application in engineering construction were comprehensively reviewed, the performance of different asphalt waterproof bonding materials were systematically investigated, and the construction technology and economy of different asphalt waterproof bonding layer materials were analyzed. This paper provides a useful reference for the specification improvement and quality control of asphalt waterproof bonding layer.
