Abstract:

The objective of this Innovations Deserving Exploratory Analysis (IDEA) project was to design a flexible pavement mixture (FPM) produced with little-to-no virgin petroleum-based binder which implied the use of high percentages of reclaimed asphalt pavement (RAP) and/or reclaimed asphalt roofing shingles (RAS), and a bio-based virgin binder. The potential impacts of a renewable (bio-based), domestic source of FPM binder on highway construction could be lower costs and, perhaps more importantly, a decreased dependence on foreign oil. The guayule (pronounced 'why-YOU-lee') plant is a perennial that grows in arid and semi-arid regions (e.g., the southwestern U.S.) and is a source of natural rubber. To validate the project concept, the use of guayule-based material in combination with high percentages of RAP and/or RAS was investigated. Based on the test results, the rubber resin produced in this study could, in a practical sense, be used as a recycling agent. FPM-production and paving industry representatives have shown interest in the results of this study and the future viability of guayule-based materials.
