Abstract
The rutting performance of asphalt pavement structure relies on the high temperature properties of asphalt mixture as well as the pavement structure and thickness. In order to investigate the influence of the structure and thickness, a full-depth wheel tracking test is developed in this research by improving the conventional wheel tracking test apparatus. The newly proposed test method is capable of varying its load speed and load size, controlling its specimen temperature gradient, and simulating the support conditions of actual asphalt pavement. The full-depth wheel tracking test based rutting performance evaluation of different asphalt pavement structures indicates that it is not reasonable to explain the rutting performance of asphalt pavement structure from the point of view of single-layer asphalt mixture rutting performance. The developed full-depth wheel tracking test can be used to distinguish rutting performance of different asphalt pavement structures, and two of five typical asphalt pavement structures commonly used in Shanxi Province were suggested for use in practical engineering.
Highlights
The Transport and Road Research Laboratory (UK) (TRRL) wheel tracking test is easy to operate and easy to understand, and the test results agree well with field test [1,2,3]
Considering the stress and strain distribution of the full-depth asphalt pavement structure with improved constraint condition are closer to actual pavement conditions under driving load than those without any improvement, the full-depth wheel tracking test with improved constraint condition is more suitable for the evaluation of the structure rutting performance
All other things being equal, the upper layer stone matrix asphalt (SMA) mixture can provide better rutting performance compared to styrene-butadiene -styrene- (SBS-)modified fine-grained asphalt mixture
Summary
The Transport and Road Research Laboratory (UK) (TRRL) wheel tracking test is easy to operate and easy to understand, and the test results agree well with field test [1,2,3]. Owing to these advantages, the TRRL wheel tracking test is widely used throughout the world. Existing researches mainly concentrated on three aspects of the wheel tracking test: (1) test temperature selection; (2) correlation between field test results and laboratory test results; and (3) correlation between TRRL wheel tracking test results and results from other high temperature performance evaluating methods [4,5,6].
