Advance Use of Recycled Asphalt in Flexible Pavement Infrastructure: Develop and Deploy Framework for Proper Use and Evaluation of Recycled Asphalt in Asphalt Mixtures
Project Information
This project will build ten test pavements with different quantities of recycled asphalt pavement (RAP), different warm-mix asphalt (WMA) technologies, and different production temperatures. The relative ranking in fatigue cracking as well as supporting laboratory characterization will guide the recommendation.
Goals
The key project objective is to quantify the cracking resistance of high RAP mixtures that considers the use of lower temperature production with WMA and recommend any limitations for combining the two technologies.
