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.
