摘　　要：沥青路面吸收了90%以上的太阳辐射,不仅会引起高温病害,还会加剧城市热岛效应,为了降低沥青路面的太阳辐射吸收率,以纳米级非化学计量含钨化合物(Cs_(x)WO_(3))为功能材料制备了一种具有良好光学遮蔽性能的新型沥青路面降温涂层,并进行了室外降温测试,评价其降温性能。结果表明:涂层中Cs_(x)WO_(3)含量越大,降温效果越显著;与未涂覆涂层的路面相比,涂覆涂层的路面结构在5 cm和15 cm深度处表现出明显的降温效果,路面整体温度可降低1~2℃,且涂层厚度影响其降温效果。Asphalt pavements absorb over 90%of solar radiation,which not only causes high-temperature diseases but also exacerbates urban heat island effects.To reduce the solar radiation absorption rate of asphalt pavements,a novel cooling coating with excellent optical shielding properties for asphalt surfaces is proposed in the paper which is prepared by using nanoscale non-stoichiometric tungsten compounds(Cs_(x)WO_(3))as functional materials,and outdoor cooling tests are carried out to evaluate its cooling performance.The results indicate that the cooling effect is more significant with higher Cs_(x)WO_(3):content in the coating.Compared to uncoated surfaces,coated pavement structures demonstrate significant cooling effects at depths of 5 cm and 15 cm,with an overall temperature reduction of 1℃to 2℃.Moreover,the thickness of the coating influences its cooling effectiveness.
