Pavement Profiler Evaluation Facility

Constructed jointly in 1999 by the Texas Department of Transportation (TxDOT) and the Texas A&M Transportation Institute (TTI), the Pavement Profiler Evaluation Facility was developed to aid in the evaluation, support, and implementation of profiling products, technology, and initiatives. Located near the skid resistance test track at the Riverside Campus Proving Grounds, the facility has about a 2,000-foot long asphalt pavement test track on which unfiltered longitudinal profiles are maintained on two wheelpaths. Over this length, the facility provides two 0.1-mile test sections with sufficient lead-ins and lead-outs for evaluating inertial profilers. Adjacent to the test track are test sections with raised steel beams of different heights for verifying and calibrating the rut bars on inertial profilers owned and operated by TxDOT.

Van Inertial Profiler

TxDOT maintains a fleet of laser/rut van-mounted inertial profilers to collect smoothness and rut depth measurements over its highway network to support pavement management activities.

Walking Profiler

Digital surveying equipment and the ARRB walking profiler are used to maintain reference profiles on the ride test track.
