- LTPP Manual for Falling Weight Deflectometer Measurements
For the analysis of FWD deflection data for research purposes, LTPP FWD operators will measure pavement temperature gradients, pavement distress, and joint crack width during the deflection testing process

The falling weight deflectometer (FWD) is a non-destructive testing (NDT) and non-intrusive device The FWD has been widely used in pavement engineering to evaluate pavement structural condition The FWD plays a crucial role in selecting optimum pavement maintenance and rehabilitation strategies
- SURFACE CHARACTERISTICS OF NEW PCC PAVEMENTS
The FWD device consists of a loading plate, weight package, geophone sensors, and data acquisition equipment Mounted to a trailer, the equipment is designed to simulate the impulse load of a passing wheel
- IRC 115: Guidelines for Structural Evaluation and . . .
Impulse loading equipment commonly known as Falling Weight Deflectometer (FWD) have been developed, which closely simulates the duration and amplitude of the load pulses
- FALLING WEIGHT DEFLECTOMETER (FWD) - PA. GOV
An FWD is a device that drops weight, of amounts controlled by the operator, onto a load plate positioned on the pavement surface (usually in the right wheelpath) and measures the deflection of the pavement with seven sensors
- NetworkFWD_FAQ_012009. qxp - Texas Department of Transportation
Network-level FWD data provides information about the structural load-carrying capacity of the pavement network It describes base and surface strength, as well as subgrade strength
- Interpreting Falling Weight Deflectometer (FWD) Data (for . . .
FWD testing performed on JPCPs is intended to assess the pavement condition prior to concrete pavement restoration or prior to placing a concrete overlay The guidelines presented here were developed for JPCP and may not be applicable for jointed reinforced concrete pavements (JRCP)
