摘要/Abstract

摘要：

基于先期建立的沥青路面温度场预估模型和车辙预估模型,利用累积车辙等效原则,提出了路面不同深度车辙等效温度的计算方法,初步建立了考虑地区差异和沥青材料特性的等效温度预估模型,并进行了检验。与国内外已有车辙等效温度预估模型相比,该模型反映了不同面层深度、不同地区及不同沥青材料类型的差异性,具有更好的适用性。

Abstract:

Rutting is closely related to the pavement temperature field. As a result, using the concept of rutting equivalent temperature to predict rutting distress is a common method. Different from previous studies, this study puts forward a calculation method of the rutting equivalent temperature for asphalt pavement at different depth, which is based upon the pre-established prediction models of asphalt temperature field and rutting distress. Meanwhile, the rutting equivalent temperature prediction model considering regional differences and asphalt material properties is initially established and tested. Compared with the existing rutting equivalent temperature prediction model, the proposed model reflects the influences of different depth, different regions and different types of asphalt materials. It is demonstrated that this model has better applicability.

Key words: road engineering, asphalt pavement, rutting prediction, equivalent temperature, prediction model
