Falling Weight Deflectometer

About Falling Weight Deflectometer

A Falling Weight Deflectometer is used to measure the vertical deflection response of a surface to an impulse load Precision load measurement and deflection sensors record the pavement surface characteristic which is used to calculate pavement properties such as Bearing Capacity Layer Thickness E Moduli Expected Surface Life FWD can also be used in determining the actual material used and in what combination to build the pavement surface It also identifies voids underneath the surface or how two surfaces typically concrete slabs are in contact with each other FWD is userfriendly with an automatic selfcheck of results data is easily transferred to PC via the USB memory key or by a direct connection Our R D team is with more than 30 years experience on pavement testing machinery well capable to customize the FWD specifications whatever on the hardware and software according to clients requests

More than 16 years R D experience we thank you for choosing LABTEST FWD for the pavement testing

The global quickest testing speed per point 3 drops is 20 seconds and available to reduce to 10s per point if fast measurement software applied

While other our local suppliers only could reach the testing speed per point3 drops to be about 40 seconds in average even compare to imported FWD with the testing speed per point3 drops about 30seconds FWD has the great advantage on the testing speed

Larger deflection range 35mm 5mm optional

Multi load control including allowable load allowable deflect height target deflect length specially for void testing

Equipped operate software with GPS function to locate the testing position precisely

Infrared PT100 temperature monitor to test the atmosphere and pavement temperature

Intellective remind function of operate software to guide the driver to park the vehicle at the right testing location

Fullyautomatic onekey operation for operator when arrived at the testing location also automatically to change into lock condition after testing process done

High deflection accuracy based on unique laser absolute calibration

Bisync lift platforms for FWD

Backup plan for each main function to guarantee better reliability

Precise Pavement Assessment

The Falling Weight Deflectometer applies a controlled impact, simulating actual vehicle loads, to evaluate road and pavement strength. This enables engineers to determine existing bearing capacity, contributing to effective pavement design and maintenance decisions. High-speed data processing guarantees reliable, accurate results instantly at the site.


User-Friendly Mobility and Data Flow

With a wheeled chassis and portable construction, the FWD can be easily moved between project locations. Its USB/PC digital output streamlines data transfer and analysis. The intuitive computerized control system, paired with dedicated software, simplifies the process of capturing, viewing, and exporting vital pavement data.
