不同级配沥青混合料传热性能的对比研究

Comparative study on heat transfer performance of different graded asphalt mixes

功能性沥青路面(绿色路面)是未来沥青路面发展的趋势,属于“海绵城市”建设范畴。多孔沥青混合料是组成功能性沥青路面的主要材料之一,在路面建设中得到了广泛的应用,其热传导特性是多孔沥青混合料的主要功能指标之一。通过研发一种新方法对不同级配沥青混合料的传热性能进行对比研究,通过数据分析多孔沥青混合料以及其他沥青混合料热阻效能不同的原因。

Functional asphalt pavement(green pavement)is the future trend of asphalt pavement development,which belongs to the category of“sponge city”construction.Porous asphalt mixture is one of the main materials of functional asphalt pavement,which is widely used in pavement construction.In this study,a comparative study of the heat transfer properties of different graded asphalt mixes was conducted by developing a new method to analyze the reasons for the different thermal resistance effectiveness of porous asphalt mixes as well as other asphalt mixes through data.
