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. Designed to simulate the impact of a rolling vehicle wheel by dropping a load pulse onto the pavement surface, the FastFWD delivers unmatched speed and efficiency in pavement testing.
Save valuable time with the Fast Falling Weight Deflectometer (FastFWD), delivering results five times faster per drop than traditional FWDs. By simulating the impact of a moving vehicle, the FastFWD provides rapid, precise data on pavement conditions, helping you make timely, informed maintenance decisions.
Its advanced load cell and deflection sensors offer detailed insights into how your pavement responds to stress.
With the Dynatest ELMOD® software, you can easily back-calculate pavement layer moduli for effective structural evaluations and overlay designs.
This combination of fast testing and accurate analysis helps you detect issues early, reduce maintenance costs, and extend the life of your infrastructure, keeping roads safer for longer.

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.
Data collected from the Dynatest FastFWD can be used to determine the structural capacity of pavements to analyze the physical properties of the road. When analyzing the data from the Dynatest FastFWD with ELMOD® software, it is possible to obtain information about the condition of the road such as: surface layers, subgrade layer, layer moduli, layer types, thickness, range of moduli, Poisson’s ratio and bearing capacity.
This information can be used to estimate overlay requirements, remaining life of the pavement, and effective creation of a Pavement Management Plan.
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.
