Characterizing RAP Binder Properties through Impact Resonance Testing of Asphalt Mixtures

In this article, the authors propose a new method of determining recycled asphalt pavement (RAP) binder properties. Common practice involves the extraction and recovery of the binder on which to perform mechanical and rheological tests, which is both time-consuming and expensive. This has created a need for alternative test methods that provide simple, fast, inexpensive, repetitive, and reliable approaches to determination of RAP binder properties. The authors' proposed method involves nondestructive impact resonance testing of laboratory compacted mix specimens with RAP and binders with known engineering properties. The study's findings confirm that testing RAP containing mixes with the nondestructive impact resonance (IR) method is among suitable techniques for determination of asphalt binder properties through mixture testing.
