Evaluation of Modified Performance Grade Binders in Thin Lift Maintenance Mixes, Surface Mix, and a Reflective Crack Relief Layer Mix

The primary objective of this research project is to design and evaluate maintenance and rehabilitation hot mix asphalt (HMA) mixes as well as develop a reflective crack relief layer (RCRL) mix utilizing modified binders. Specifically, thin lift mixes with a NMAS of 4.75 mm and 9.5 mm and a surface mix with a NMAS of 12.5 mm will be developed as maintenance and rehabilitation mixes using Superpave design methodology. These mixes will then be evaluated for their resistance to low temperature cracking and rutting. The secondary objective is to compare the performance of these modified mixes. Finally, a RCRL mix will be developed and tested for its potential to prevent or mitigate reflective cracking.
