Modified Asphalt Binders - How Do They Compare?

by Randy C. Ahlrich, (M.ASCE), US Army Engineer Waterways, Experiment Station, Vicksburg, United States,

Document Type: Proceeding Paper

Part of: Aviation Crossroads: Challenges in a Changing World

Abstract:

This report summarizes some of the research that the US Army Engineer Waterways Experiment Station (WES) has conducted on asphalt modification of airport/airfield pavements. these laboratory studies and field evaluations were conducted for the US Air Force and the Federal Aviation Administration (FAA). Asphalt modified mixtures were tested and evaluated to determine the potential of asphalt modification to reduce pavement permanent deformation (rutting) and to improve rheological properties (decreasing thermal cracking).
