Evaluation of the Rutting Performance of the Field Specimen Using the Hamburg Wheel‐Tracking Test and Dynamic Modulus Test

Abstract

Rutting is a major distress occurring in the service life of the asphalt pavement, especially in hot weather areas. A laboratory-produced specimen is widely used for rutting performance evaluation which may not be completely represented by the field situation. The objective of this study is to evaluate the rutting performance of field specimens from the Chongqing highway by utilizing the Hamburg wheel-tracking test (HWTT) and dynamic modulus test. Different test conditions were conducted on the HWTT by investigation of the actual local weather condition. The results showed that rutting depth was different under different test conditions, and 10000 loading cycles were recommended as the maximum loading cycles. Particularly, several factors that influence the rutting depth were investigated, and the specimen height of 6 cm is more appropriate for the HWTT. Additionally, different test conditions were proposed as the HWTT test condition for different asphalt concrete (AC) layers in the Chongqing area. Rutting contribution of each AC layer to the pavement structure was analyzed. Moreover, the dynamic modulus at 54.4°C, 5 Hz and 54.4°C, 1 Hz could effectively represent the rutting performance of the asphalt mixture, and the dynamic modulus test is recommended for the rutting performance evaluation of the full-thickness AC layer.

Investigation of Permanent Deformation Behavior of Steel Slag Asphalt Mixture under Indoor Simulation

“…Asphalt pavement during service life is prone to crack and damage due to heavy load, overload, high temperature, and water erosion, resulting in rutting disease and affecting its driving comfort and safety [1,2]. en, the further development of rutting will also cause other diseases such as network cracks and pits, which will seriously reduce the structural performance and service performance of asphalt pavement [3,4].…”

Establishment of Rutting Model of Wheel‐Tracking Test for Real‐Time Prediction of Rut Depth of Asphalt Layers

“…Rutting is one of the main early distresses in asphalt pavements, which not only significantly reduces the service quality and service life of the road but also poses a serious threat to the driving of the vehicle [1][2][3]. rough investigation, it was found that bad construction quality of the asphalt layer is one of the main reasons for the early distresses in asphalt pavement [4,5].…”
