State Materials Office
Overview
The Pavement Performance Unit is responsible for evaluating the friction characteristics and structural adequacy of in-service pavement systems. Each year, specialized friction units are used to test 7,500 to 8,000 lane miles of the State Highway System, all new construction projects, and airport runways in support of the Department’s Safety Program. This testing is used to monitor the friction characteristics of pavements on an annual basis, identify spot hazard locations, and assess the needs for runway rubber removal. For pavement structural adequacy evaluations, Falling Weight Deflectometer (FWD) devices are typically used to support the District Design Offices primarily in the design of resurfacing projects. This functional Unit is also equipped with additional specialized equipment such as the Automated Dynamic Cone Penetrometer (ADCP), and the Ground Penetrating Radar (GPR), for in-depth forensic and geophysical investigations.
