摘要
通过对复合式路面与半刚性基层沥青路面的沥青层温度场对比研究,可为复合式路面或"白改黑"路面(旧水泥混凝土路面加铺沥青面层)沥青层的设计及施工提供技术支持。将沥青层看作是厚度和材料不全相同的2～3层,然后逐层研究分析,结果表明两种路面结构沥青层的温度场非常相似,认为温度作用下复合式路面沥青层的设计及施工经验可借鉴半刚性基层沥青路面。
The comparative Study of asphalt layer temperature field of combined type pavement and asphalt pavement with semi -rigid base course could provide support for design and construction of asphalt layer of com- bined type pavement or ＂change white to black＂ pavement （paving asphalt surface on old cement concrete pave- ment）. Taking the asphalt layer as 2 -3 layers with not totally same thickness and material, each layer is studied and analyzed one after one. The result shows that the temperature field of asphalt layer of the two pavement struc- ture is very similar and the design and construction of asphalt layer of combined type pavement affected by tempera- ture could take that of asphalt pavement with semi - rigid base course as a reference.
