Focus on Preservation at NCAT Pavement Test Track Meeting

Pavement Preservation Journal, Summer 2015, Vol. 8, No. 2

By Dr. Mary Robbins

Research findings from the half-mile stretch of experimental roadway dedicated to pavement preservation in Auburn, Ala., were revealed at the National Center for Asphalt Technology Test Track Conference. The 2½-day conference took place March 3-5 at the Auburn University and Dixon Conference Center.

Participants from local, state, and federal agencies – as well as the private sector – turned out in record numbers for a chance to tour the facilities and learn about advancements in asphalt pavement design, construction, technologies and maintenance. Held every three years, this was the fifth conference NCAT has hosted, and saw attendance grow to over 260 attendees, a 60 percent increase from the previous conference.

Pavement preservation research at NCAT began in summer 2012, initiated, sponsored and underwritten by seven state DOTs, FP2 Inc. and its financial supporters.  This research has the potential to scientifically quantify the life-extending benefits of pavement preservation for flexible pavements, and evaluates the benefits of a comprehensive list of pavement preservation treatments.

The focus of the second day of the conference was on pavement preservation research at NCAT. The day began with an introduction to the extensive work being conducted on Lee Road 159, and then group tours to the site provided participants with an opportunity to see firsthand the life-extending and condition-improving benefits of the wide range of treatments being investigated.
