Field Performance of Pavements Made with High-Modified Hot Mix Asphalt Mixtures

The objectives of this research project are to: (1) measure the mechanical response to traffic loads of the High-Modified Hot-Mix Asphalt over rubblized concrete base on a portion of the I-215 west belt project near Salt Lake City, Utah, (2) measure the deformation of rubblized base and existing base due to traffic loads (3) document the short-term performance of the pavement system, and (4) verify the models and assumptions used to design this pavement section by comparing the predictions to actual measurements. At the conclusion of this project, Utah Department of Transportation (UDOT) pavement and materials engineers will have a better understanding of the behavior, and thus the applicability, of high modified hot-mix asphalt mixtures to high-value roads.

• Supplemental Notes:
  • This research project is mainly funded with SPR-B funds through UDOT. A UTC through the University of Utah may provide supplemental funding on separate contract.
