A rolling weight deflectometer for quantitative pavement measurements
The bending-compensated rolling weight deflectometer (RWD) is a new method to rapidly and accurately assess pavement strength. It is currently being evaluated for use on airfield pavements for testing new pavements and assessing repaired ones. A highway RWD is envisioned that would have the following features: 13 m/s (30 mph) or greater speed, pavement temperature coherent to deflection point, axle load and acceleration, ability to measure the shape of the deflection basin using additional pavement sensores, a higher-speed date acquisition network, and automatic power control of lasers in pavement sensors.
