Development of Aging Resistant Binder Technology

Project Information

Project ID: 
Project Abstract: 

This project is aimed at developing a new category of additives that inhibit the damaging effects of aging asphalt binders that lead to cracking and raveling of flexible pavements. Four industrial partners and two univeristy-affiliated research groups have teamed together to scientifically evaluate the technical and commercial feasibility of six promising technologies. The anticipated outcomes of the study will be two-fold. First, the research will expedite development of promising aging-resistant additivies for asphalt binders and move those toward implementation. Second, the research will establish standardized methods for evaluating future products aimed at providing similar benefits. The ultimate potential impact of this research will be asphalt pavements with much longer service lives and therefore a substantial reducation in the cost of maintaining the Nation's pavement infrastructure.
