Design System for HMA Containing a High Percentage of RAS Material

The primary objective of this research is to develop and validate a simple design system for hot mix asphalt (HMA) containing a high percentage of reclaimed asphalt shingles (RAS). More specifically:(1) Develop a test method to quantify the contribution of RAS binder to the HMA blended binder properties without the use of chemical solvents to extract the asphalt binder from the RAS. (2) Determine the effect of combining RAS and reclaimed asphalt pavement (RAP) on blended binder properties. (3) Create an analysis tool, or spreadsheet, that will allow users to estimate the effect of varying levels of RAS binder on the blended binder.
