Asphalt Mix Compaction Modeling
Project Information
Phase I Technology Review, Model Selection. This project will identify mathematical models that could be applied to the compaction of hot-mix asphalt (HMA) and modify them to be suitable for modeling HMA compaction. Phase II will include: input determination, verification/calibration, sensitivity analysis/development of guidelines, and final report. This phase will identify parameters to be determined or estimated for the model selected in Phase I and perform a sensitivity study on the parameters. The intended outcomes of the project are to theoretically relate laboratory and field compaction; understand the important parameters in obtaining density without sacrificing performance; and improve the construction process to obtain the optimum in-place density. Researchers are collaborating with United States Department of Energy Argonne National Laboratory to utilize its Transportation Research and Analysis Computing Center (TRACC) cluster for computational capabilities.
Goals
Address the gaps in the calibration inputs for previously completed "Modeling of Hot-Mix Asphalt Compaction: A Thermodynamics-Based Compressible Viscoelastic Model."
