【摘要】 沥青材料是一种吸热材料,它对太阳光辐射的吸收率很高,在夏季会造成沥青路面温度远远高于气温,由此引发沥青路面车辙危害。沥青路面热反射涂料是降低沥青路面温度的”主动”降温方式,它的应用可以减少车辙危害,并在一定程度上缓解城市”热岛效应”。本文在国内外相关热反射涂料研究的基础上,通过系列实验研究,了解了沥青路面热反射涂料的组成体系并确定了性能表征和性能测试方法,最后确定合理的试验配方。论文工作主要有以下几方面:1)查阅国内外相关研究报告,系统地分析了沥青路面的光热环境、热阻效应以及太阳光对沥青路面材料的辐射和防辐射机制;2)以沥青路面材料的降温、抗滑、耐水、耐磨擦性为评价指标,确定沥青路面热反射涂料的系统配方组成,制备出了满足性能要求的热反射涂料;3)对所制备的沥青路面热反射涂料进行了系统的测试分析;4)通过系列试验确定了沥青路面热反射涂料的涂装施工工艺并进行了成本估算分析。试验结果表明所制备的沥青路面热反射涂料能够满足沥青路面的使用要求,为进一步扩大实际应用可提供理论依据和试验基础。

【Abstract】 The asphalt is a kind of hear absorption material, and has a high absorption of solar radiation, which can make the temperature of asphalt pavement much higher than the air temperature in summer and cause rut harm of asphalt pavement. In this article, a kind of heat-reflection coating of asphalt pavement is researched and designed to reduce the temperature and rut harm of asphalt pavement, ease the“urban heat island effect”of cities to some extent.In this paper, a reasonable experimental formula is determined based on studying of research information of heat-reflection coating domestic and overseas, experimental series, and understanding in composition system, performance characterization and performance test of heat-reflection coating of asphalt pavement. The following research works have been carried out:1) Read the related memoir of domestic and foreign, analyze the light-hot environment and the thermal resistance effect of asphalt pavement, and aggregate the solar radiation and anti-radiation mechanism on asphalt pavement.2) Determin a formula composition and prepare the heat-reflection coating of asphalt pavement which meets the requirements of performances on temperature decreasing, antiskid, water resistant, and wear resistant.3) Test and analyze the asphalt pavement heat-reflection coating.4) Determine the painting technology of asphalt pavement heat-reflection coating based on a series of experiments and achieve the cost estimate analysis.The resualts shows that the heat-reflection coating of asphalt pavement prepared in the experiments has meet the requirement of asphalt pavement ,which provide experimental foundation to further research and practical application.
