CFME T2GO

CFME T2GO — Continuous Friction Measurement Equipment

The CFME T2GO is a trailer-based Continuous Friction Measurement Equipment (CFME) used to measure pavement skid resistance (friction coefficient μ) continuously at highway speed. A locked or free-spinning test wheel is towed behind a vehicle, and friction is measured as the ratio of longitudinal friction force to vertical load.

JS Civil Lab Solutions supplies the CFME T2GO for runway safety surveys, NHAI highway QC, and road safety audits across India.

Technical Specifications

• Measurement: Longitudinal friction coefficient (μ)
• Test wheel: Smooth tyre, 15° slip angle (SCRIM principle) or locked-wheel method
• Survey speed: 40–80 km/h
• Water delivery: Onboard tank with controlled wetting rate (1 mm water film)
• GPS recording: Continuous chainage correlation
• Standards: ASTM E274, EN 13036-2, ICAO Annex 14 (for runways)

Why Skid Resistance Testing Matters

Low skid resistance increases stopping distances and crash risk, particularly in wet weather. MoRTH and NHAI specify minimum friction values (μ ≥ 0.45 on expressways) that must be maintained throughout the pavement life. CFME surveys identify deficient sections for surface treatment or retexturing.
