The Feasibility of Asphalt Pavement Rejuvenator Applications

With shrinking budgets and higher oil prices, agencies such as local governments and private Homeowners Associations struggle to maintain their asphalt roadways.

This study’s intended audience are such agencies and the intention is to contribute to their respective pavement management programs by analyzing a method that will extend the life of their asphalt roads and maximize their maintenance investment. The objectives of this study are to identify the barriers of using asphalt rejuvenators as a method of road maintenance and determine its optimal use and feasibility.

Data was gathered and analyzed from numerous applications and laboratory tests performed on rejuvenators since its introduction to the industry in the 1960’s. In addition, the experience of a local government agency with the use of rejuvenators was studied, in order to design a feasible method of application with the goal of maximizing road maintenance budgets. Conclusive history shows that the use of rejuvenators can extend the life of asphalt pavement.

Using these guidelines, pavement life can be extended by 8 years resulting in savings of 29% on the life cost of the treated pavement. It should be noted that this is a savings realized over the life of a road candidate for the method of rejuvenation and not an overall maintenance budget savings.
