2258 - Evaluate Densifier-Over-Shotblasting (DOS) Treatment Performance for Pavements and Bridge Decks

With increased demands on aging infrastructure, rapidly increasing truck traffic, and shrinking budgets, transportation agencies are continually being asked to "do more with less" in maintaining pavements and bridges. The proposed research provides a method for combining chemical treatment (densifier) and shotblasting, called Densifier-Over-Shotblasting (DOS), to economically harden the aggregates of concrete and asphalt pavements and bridge decks. The proposed DOS method will make surfaces safer and more durable, reduce maintenance costs and increase service life of pavements and bridge decks. The proposed study will have the following major benefits: (i) specifications of the required characteristics of DOS; (ii) identification of polishing tendency of aggregates that are available in each Oklahoma Department of Transportation (ODOT) division; and (iii) documentation of effective construction practice and Inspector's guide.
