Accurate and repeatable CFME test device. Designed for continuous fixed-slip friction testing on roads and highways, providing coefficients of friction on highway pavements meeting the ASTM E2340 Standard.
The Dynatest 6875H Highway Friction Tester (HFT) is designed for measuring skid resistance and evaluating road surface grip on highways – as well as testing to evaluate changes in highway pavement friction characteristics caused by traffic and environmental factors (e.g. weathering, polishing, aging, contaminants). Operating as a Continuous Friction Measuring Equipment (CFME), it uses a fixed-slip testing technique (13–15% slip ratio) to measure skid resistance continuously along entire road sections.
This fully integrated system provides accurate, repeatable friction data at highway speeds, enabling road authorities to identify slippery or low-friction areas and implement targeted safety improvements. Compliant with ASTM E2340 (standard method for continuous fixed-slip friction testing), the HFT helps ensure highways meet safety standards. The continuous friction profile it produces is especially valuable for spotting friction variations on critical segments (e.g. bridge decks, off-ramps, intersections) that discrete testing might miss.
You need it when:
Network-wide road safety surveys: Continuous friction testing of highways or major roads to monitor skid resistance along entire sections, complying with CFME standards (e.g. ASTM E2340). This provides a complete friction profile instead of isolated data points.
Identifying hazardous stretches: Evaluating friction on high-risk road segments (sharp curves, ramps, bridge decks) to detect slippery areas early and prioritize anti-skid treatments or resurfacing. rd]
Routine pavement friction monitoring: Tracking friction changes over time due to pavement wear or contamination and integrating results into accident prevention strategies and pavement management systems.
The Dynatest Highway Slip Friction Tester (HFT) is an accurate and repeatable test device that provides coefficients of friction on highway pavements.
It is designed for maintenance testing to evaluate pavement friction changes due to weathering, traffic, aging, and contaminants. It can be used in difficult test areas, such as bridge decks, off-ramps, city streets, and intersections, giving an accurate continuous friction trace for the area being tested.
The Highway Slip Friction Tester is particularly important during adverse weather conditions, such as rain, snow, or ice when the pavement surface can become slippery and reduce a vehicle’s ability to stop or maneuver safely. The data can then help engineers and maintenance crews make informed decisions about the suitability of the road surface for safe vehicle travel.
