道桥施工中防水层技术研究

Research on waterproof layer technology in road and bridge construction

道桥质量问题大多源于防水系统的破坏。大量实例表明,道桥防水层受损主要由设计、材料、施工技术等问题引起。本文通过对防水层施工技术的分析、新型防水层和防水材料的介绍及相关规范的解读,讨论如何提高道桥防水层质量。

Most of the quality problems of roads and bridges originate from the damage of waterproof system.A large number of examples show that the damage of waterproof layer of roads and bridges is mainly caused by problems from design,material and construction technology.Based on the analysis of the construction technology of waterproof layer,the introduction of new waterproof layer and material,and the interpretation of relevant specifications,this paper discusses how to improve the quality of waterproof layer of roads and bridges.
