Mechanical Properties of Warm Mix Asphalt Prepared Using Foamed Asphalt Binders, Executive Summary

摘要

The main objectives of this study are: (1) Develop a procedure by which WMA-FA mixtures can be produced in the laboratory; (2) Evaluate the performance of WMA-FA mixtures with regard to moisture susceptibility and permanent deformation; (3) Evaluate the performance of control HMA mixtures prepared using the same aggregates and asphalt binders; (4) Compare the performance of WMA-FA and HMA mixtures; and (5) Recommend changes to current ODOT practices and specifications to address the research findings.
