摘要: 沥青路面的力学性能同其温度场有着密切的联系。城市热岛效应是同样大气条件下的局部高温温度场,在 其影响下,市郊沥青路面结构的温度场将存在温度差,其力学性能将出现变化,从而导致市区的路面比郊区的路面 更容易出现破坏。为了验证这种影响,实测了在夏季高温季节时沥青路面结构中的热岛强度,并通过轮辙试验及加 速加载试验考察其对沥青路面抗变形性能、车辙试验验收标准及沥青路面结构设计过程中沥青结合料选择的影响。

关键词: 沥青路面, 温度场, 热岛效应, 轮辙试验, 加速加载试验

Abstract: The performance of asphalt concrete pavement is closely related to the temperature. The urban heat island, a local high temperature field, would lead to temperature difference between the city and the suburbs. Changes of mechanical properties caused by temperature difference would make urban asphalt pavement more fragile than the suburban one. In order to verify the case, the heat island intensity of the asphalt pavement structure in summer was measured, the influence of the intensity on resistance of deformation, selection of asphalt and standard of dynamic stability was studied through acceler?? ated pavement test and rutting test

Key words: asphalt concrete pavement, temperature fields, urban heat island, rutting test, accele rated pavement test
