Rutting prediction of asphalt pavement with semi-rigid base: Numerical modeling on laboratory to accelerated pavement testing
https://orcid.org/0000-0002-8561-7223
Highlights Rutting development is predicted using laboratory-based and multi-scale tests. Triaxial tests predict the rheological properties of asphalt at high temperatures. Modified Burgers FE model considers the damage effect of the asphalt mixture. Permanent deformation and rutting depth of the asphalt pavement are monitored. The computationally efficient method can aid long-term maintenance of pavements.
Abstract Rutting development and its prediction are critically important for the long-term preservation of semi-rigid pavements. A multi-scale test was developed to analyze the rutting development and its prediction model, involving triaxial, scaled loading, and full-scale loading tests. Laboratory-based triaxial tests predicted the rheological properties of asphalt mixtures at high temperatures. The flow number F N was only related to the cohesion and internal friction angle, confining pressure, and circulating pressure of the mixture. Rutting prediction models were established using a modified Burgers finite-element model and verified through scaled and full-scale loading tests. The relationship between F N of the dynamic creep test and loading times of scaled and full-scale loading test were determined through comparative analysis. Finally, the cross-scale relationship between the multi-scale tests was established by introducing correction coefficients K 1 and K 2. The proposed prediction model of rutting development is suggested to be computationally reasonable, which could provide a scientific reference for the treatment and maintenance of rutting on asphalt pavements.
