For High Quality Roads & Airports Pavements, The Heavy Weight Deflectometer (HWD) Equipment Is Available At ACTS Branches In KSA

The Heavy Weight Deflectometer (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 modelling
• In pavement management
• In pavement research​

Key Benefits

• 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
