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.
High-Speed Deflection Testing in the Field
The Dynatest Fast Falling Weight Deflectometer (FastFWD) is engineered for rapid structural assessment of pavements. By simulating the dynamic load of a moving wheel through a segmented loading plate, the FastFWD delivers drop rates up to five times faster than traditional FWDs—enabling efficient data collection without compromising accuracy.
Standard features include a four-segmented swivel-mounted load plate for uneven or rutted surfaces, air and pavement temperature sensors, a Distance Measuring Instrument (DMI), and an onboard generator for fully autonomous operation in the field.
Structural Analysis with ELMOD® Integration
When combined with Dynatest’s ELMOD® software, the FastFWD provides a complete solution for calculating pavement layer moduli, conducting structural evaluations, and designing overlays.
The system gives you clear insight into pavement behavior under load, allowing for early detection of structural issues and better-informed maintenance planning—helping to preserve performance and extend service life.

Want to know what makes the FastFWD stand out? Watch our new product video to see how it performs in the field, integrates with DynaWare, and helps you save valuable time on every test.
DynaWare improves the current user interface of the Fast Falling Weight Deflectometer and elevate the electronics, hardware, and software to modern standards.
Thanks to DynaWare it is possible to offer advanced GIS visualization when collecting data and when planning survey routes. DynaWare brings a complete hardware redesign and wirings will be drastically reduced.
Immediate AI-based inspection of any detected fault of the geophones makes troubleshooting easier and faster.
Dynatest’s ELMOD® software delivers a full suite of structural analysis tools for flexible, rigid, and composite pavements.
Fed with FastFWD load-deflection data, it reduces and interprets each drop sequence in under a second, back-calculating layer moduli, correcting them for seasonal effects, estimating residual pavement life, and recommending overlay thickness aligned with the desired service life.
For maintenance and repair planning, the built-in Life-Cycle Cost Analysis module compares alternative strategies and selects the option with the most favorable cost-to-benefit ratio for each pavement section.
In aviation applications, ELMOD® simultaneously reports the emerging ACR/PCR classification and the traditional ACN/PCN values, giving airfield managers a seamless path through the FAA’s transition period until ACR/PCR becomes fully mandatory in November 2024.
Since the year 1900, Accelerated Pavement Testing (APT) has played a crucial role in fostering innovation and enhancing our understanding of pavements through accelerated testing, and is a valuable tool that can be utilized to predict and validate pavement performance. The possibility of using the FastFWD for Accelerated Pavement Testing (APT) to study pavement deterioration will shorten the gap between the Heavy Vehicle Simulator (HVS) and small-scale laboratory test methods.
The FastFWD (with an APT application package) has proven to be able to be used as an intermediate tool, between small-scale laboratory tests (bending beam, shear, and triaxial tests) and full scale accelerated pavement tests. Several tests have been conducted with great success. Read more about this application in the brochure or application note below.
