An Acoustic Emission-Based Test to Determine Asphalt Binder and Mixture Embrittlement Temperature
This Innovations Deserving Exploratory Analysis (IDEA) project focused on the development of a simple and practical Acoustic Emission-based (AE-based) testing method for the accurate and rapid characterization of the cracking behavior of asphalt binders and hot mix asphalt. The test method could also be implemented to characterize modern warm mix asphalt and mixtures with high amounts of recycled asphalt pavement (RAP), to help ensure the durability of these environmentally friendly materials. Phase 1 of the project focused on the standardization and validation of the method for binder testing along with the development of an improved prototype of an asphalt embrittlement device. In phase 2, techniques for using the AE-based device for the characterization of asphalt mixtures were developed.
