Impact of Truck Loading on Design and Analysis of Asphaltic Pavement Structures -- Phase IV

The goal of this research is to advance current practices in the selection of paving materials and design-analysis methods of pavement structures based on more realistic fundamentals of the effects of heavy-load trucks on pavement damage and performance. Trucking is the most dominant component of U.S. freight transportation and is expected to grow significantly in the future. Better protection of highway infrastructure against heavy-load trucks is therefore necessary, and success can be achieved by a more accurate and realistic understanding of the pavement performance associated with damage. In particular, this study targets a more realistic performance prediction of pavement cracking (fatigue cracking and thermal cracking). To meet the objective, the rate-, mode-, and temperature-dependent fracture behavior of asphaltic materials is characterized based on an integrated experimental-computational approach. Appropriate fracture tests are conducted, and the experimental efforts are then integrated using advanced computational modeling. Findings from this research are expected to improve actual practices in the selection of more engineered paving materials and in more advanced implementation of current design and analysis methods, which will eventually contribute to safer, more efficient, more effective, and more sustainable U.S. roadway infrastructure.
