HWD
Heavy Weight Deflectometer
The HWD is highly versatile and can be used to test on both rigid, paver block, and flexible pavements on roads and airports.
The HWD is highly versatile and can be used to test on both rigid, paver block, and flexible pavements on roads and airports.
Dynatest developed the first commercially available Heavy Weight Deflectometer (HWD). The HWD is highly versatile and can be used to test on both rigid, paver block and flexible pavements on roads and airports. The HWD can apply a loading in the range of 30-320kN, enabling it to simulate vehicle loading from to the most extreme aircraft wheel load such as the Boeing 777, the Airbus 340, or 380.
The output from the deflectometer can be used:
To determine the layer of failure and the optimum rehabilitation solutions.
For quality control or existing and new pavement construction
Improve and understand pavement modeling
In pavement management
In pavement research
Dynamic loading enables mechanistic-empirical analysis of the pavement layers and the determination of optimum rehabilitation strategies
Automated and rapid structural pavement testing
Determines the layer of failure, rather than determining simply the bearing capacity
QA/QC of newly built pavements
Compares a range of rehabilitation options, including plane off and recycling rather than just applying overlays
The Dynatest HWD provides accurate, reproducible, and repeatable data
Automated and real-time monitoring of the load cell, geophones, and data variations ensures high quality of collected data
Uses mechanistic analysis allowing testing of most pavement structures
The HWD is used worldwide from the hottest and driest deserts to the humid tropics and the cooler polar regions
