Rolling dynamic deflectometer
WebMicrosoft WebUsing ground-penetrating radar (GPR), TTI’s total pavements acceptance device (TPAD) automated rolling deflectometer and core sampling, TTI evaluated the health of all the affected roadways. SH 6 was first. It carries tens of thousands of vehicles each day, so getting it open was critical.

WebThe Federal Highway Administration began funding Rolling Wheel Deflectometer (RWD) development in the late 1990s. This device consists of a 53-ft semi trailer with a dual-tire, 18-kip single axle that has been instrumented with several generations of deflection measuring systems, including a scanning laser, spot lasers, and most recently ... WebThe Rolling Dynamic Deflectometer (RDD) is a continuous pavement deflection profiling device that evaluates the existing structural condition of pavements. As the RDD moves along the pavement, it dynamically loads the pavement, and multiple rolling sensors simultaneously measure the induced dynamic deflection of the pavement.
