Abstract:

The Western Transportation Institute (WTI) conducted research on behalf of the New Mexico Department of Transportation (NMDOT) to document current knowledge and practice related to evaluation of plus grades of performance graded (PG) asphalt binder, with a focus on the scenarios of interest to NMDOT. This synthesis mainly includes a discussion of the following issues: history of polymer modified binders (PMBs) for asphalt pavement, selection of polymer for asphalt modification, evaluation of PMB properties, binder specifications for PMBs, cost analysis, recommendations, and future work. Recent years have seen the introduction of PG Plus Binders, the success of which hinges on the use of elastomer and/or rubber for binder modification. NMDOT is strongly recommended to apply elastomer modification right now while optimizing the formulation and adopt Multiple Stress Creep Recovery (MSCR) into the binder specification and implement plus grades of PG asphalt binder, in light of very small cost increase (less than 5%) and significant performance improvements (over 20% life extension) in plus-grade asphalt pavement.
