There’s a reason we call it “fast.”
The Dynatest Fast Falling Weight Deflectometer (FastFWD) isn’t just quick—it’s up to five times faster per drop than the original FWD and outpaces anything else on the market.
The FastFWD is designed to impart a load pulse to the pavement surface simulating the load produced by a moving vehicle. The load pulse is measured by a load cell with a resolution of 0.1 kPa, and the pavement response is recorded by up to 15 deflection sensors with a resolution of 0.1μm.
The post-processing software (i.e. Dynatest ELMOD- Evaluation of Layer Moduli and Overlay Design) can be used to back-calculate the pavement layer moduli based on the impact load and surface deflection basin. The results can effectively be used for the evaluation of pavement structural condition and overlay design based on empirical or mechanistic-empirical pavement design guides.
- Perform tests at five times the speed of a traditional Falling Weight Deflectometer (FWD), dramatically increasing productivity.
- Lower operational costs due to faster testing, reduced manpower requirements, and less downtime.
- Meets AASHTO R 32 and has passed the UK Correlation Trial, confirming its accuracy and reliability.
- A simpler, cleaner design eliminates the need for hydraulic systems, reducing complexity and potential failure points. Also, fewer mechanical components and no hydraulics mean lower long-term operating expenses.
- Existing Dynatest Model 8002 FWD units can be upgraded to FastFWD, offering a cost-effective path to enhanced performance.
