摘要:
针对缺乏完备的路用涂层耐久性评价指标体系问题,全面调查和梳理了现有涂层标准及规范中对于耐久性相关评价要求。深入分析当前涂层耐久性评价中存在问题,选择环境和行车作为主要影响因素,明确单一指标组成及分类,通过不同单一因素的合理组合及匹配性分析,确定复合工况下的路用涂层耐久性综合评价指标;结合中国现有涂料性能的评价指标和方法,提出路用涂层材料单一及复合工况条件下的耐久性评价试验方法,并基于涂料的性能参数和试验结果确定路用涂层的耐久性评价指标限值及相应的评价使用范围;建立系统和完备的道路用涂层材料的耐久性评价指标体系和方法,并采用提出的耐久性评价指标对道路用涂层材料实际应用过程中的耐久性能进行全面评价和研究。结果表明:该路用涂层耐久性评价体系指标与路用涂层材料的实际应用环境具有良好的匹配性,可针对路用涂层在复杂应用环境中的耐久性进行室内模拟和全面评价,为路用涂层的耐久性评价提供了合理的试验方法;采用相关评价指标和方法获得的耐久性评价结果与实体工程应用效果基本一致,该耐久性评价指标及方法具有良好的理论基础,能够为现有路用涂层耐久性评价提供依据。
Abstract:
Regarding the lack of a durability evaluation system for pavement coating, the evaluation indices and requirements of the current standards were comprehensively investigated and summarized. The problems of durability evaluations of coatings present in the current standards were analyzed. The environment and vehicle load were selected as the main influencing factors, which cleared the composition and classification of a single indicator. Through a reasonable combination and matching analysis of different single factors, a comprehensive evaluation index of the road coating durability under composite working conditions was determined. Combined with the evaluation indices and corresponding methods of the existing coating properties in China, durability evaluation test methods for road coating materials 〖HJ〗under single and composite working conditions were proposed. Based on the performance parameters and test results of the coatings, the durability evaluation indexlimits of the road coatings and the corresponding evaluation scope were determined. Finally, a method for the road coating materials and the complete durability evaluation index system and a method for the road coating materials were established. The durability evaluation indices proposed were used to comprehensively evaluate and study the durability of the road coating materials. The results show that the road coating durability evaluation indexsystem matches well with the practical application environment of the road coating material. An indoor simulation and a comprehensive evaluation of the durability of the road coatings in complex application environments provided reasonable test methods. The durability evaluation results obtained using relevant evaluation indicators and methods are basically consistent with the physical engineering application results, indicating that the durability evaluation indicators and methods can provide a scientific and objective basis for a durability evaluation of existing road coating applications. 8 tabs, 20 refs.
