Full-Scale Evaluation of Fiber-Reinforced Hot Mix Asphalt

Funding Agency: DOD

Abstract:  The goal of this research study is to evaluate the fracture behavior and full-scale field performance of fiber-reinforced HMA mixtures. A secondary goal of this study is to further understand the impact of fiber type and oxidation on the performance of fiber-reinforced HMA.

• Assess fracture properties of fiber-reinforced asphalt mixture using laboratory fracture (intermediate and low temperature) testing and Digital Image Correlation (DIC)
• Conduct full-scale field testing on fiber-reinforced HMA mixtures using Rowan University Accelerated Pavement Testing Facility (RUAPTF)
• Investigate the laboratory short- and long-term oxidation on intermediate and low temperature cracking performance of fiber-reinforced asphalt mixtures.
• Conduct Life-Cycle Cost Analysis (LCCA) of fiber-reinforced asphalt mixtures
