Interest from New Jersey DOT, research performed by Rutgers University, and cooperation from suppliers and contractors, has turned HPTO into the “work horse” of the NJDOT pavement preservation program. Since 2015, NJDOT has used HPTO on more than 1,000 lane miles to seal pavement and improve ride quality. Agency staff say it causes minimal impact on traffic with short road closures, and adds approximately 10 years service life.

NJDOT uses HPTO to keep up with increased traffic demands without adding depth to the pavement. This is significant because the Department of Environmental Protection rarely allows the agency to raise road elevations. NJDOT uses HPTO in areas with vertical clearance concerns, guardrails, and curb and gutter. Including performance requirements for the mixture, successful construction practices, and requiring the project engineer to approve specifications, are believed to be key factors in the success of HPTO as a pavement preservation tool in New Jersey.

NJDOT’s Robert Blight will share many lessons learned during the webinar. In this short video, Blight explains how the agency overcame funding challenges to create a strong pavement program that incorporates targeted overlay pavement solutions.
