Effect of Post-Consumer Recycled Asphalt Shingles on Pavement Performance

Purpose:  This project would entail researching and gathering aggregates, asphalts, recycled shingles and recycled asphalt pavements from around PA.  The gathered materials would then be used to create samples that would be evaluated for low and high temperature performance.  Some samples would be made with no post-consumer recycled shingle materials and some would be made with varying percentages of post-consumer recycled shingles and recycled asphalt pavement.  The effects on the cold weather fracture energy (cracking) and rutting potential would then be compared and allow PennDOT to establish limits for performance testing that would allow the use of post consumer recycled shingles with little or no effect on performance.

Design - Project No: EO3723 WO 001

Anticipated Outcomes
The expected outcome of the project will allow PennDOT to use post-consumer recycled asphalt shingles with little or no effect on pavement performance, reduce paving and maintenance costs and help lower environmental impact by making use of recycled asphalt shingles.
