Team:   Pavement Materials Team [HRDI-10]
Program:   Innovative Pavement Research and Deployment
Laboratory:   Binder Laboratory
Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   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 Recycled Asphalt Pavement (RAP) mixtures that considers the use of lower temperature production with warm-mix asphalt (WMA) and recommend any limitations for combining the two technologies.
Product Type:   Draft standard, specifications, or guidelines
Research report
Test Methodology:   Full-scale accelerated pavement testing, laboratory tests and experimental design, test protocol development, ruggedness study, develop precision, and bias statements.
Expected Benefits:   New protocol for evaluating high Recycled Asphalt Pavement (RAP) asphalt mixtures and determining RAP limits and binder performance grade needs.
