Bexar County applies a fundamental tenet of pavement preservation, that is, for the lowest-cost, long-term performance, treat roads before they show distress. Bexar (pronounced "bear") County includes urban as well as rural pavements, as the City of San Antonio is located there. Accepting the award for the state of Tennessee was Tennessee DOT Commissioner John Schroer. The DOT was honored for its outstanding advocacy for, and implementation of, its statewide pavement preservation program. In only four years – between 2007 and 2011 – Tennessee DOT transitioned from an almost exclusively hot mix asphalt resurfacing program to one that incorporates pavement preservation principles. The result has been a significant improvement in pavement condition. The department provided detailed pavement management systems data to prove the case for future network condition, and worked with the local hot mix industry to develop new specifications for thin hot mix overlays to gain its buy-in to the program. These thin hot-mix overlays now have become another routine pavement preservation treatment used in Tennessee.
