Dec 17, 2025 · HFST involves the application of very high-quality aggregate to the pavement using a polymer binder to restore and/or maintain pavement friction at existing or potentially …

The High Friction Surface Treatment Association is the leading organization for the promotion and installation of high quality, long-term, durable High Friction Surface Treatments (HFST).

HFST has a much higher coefficient of thermal expansion than concrete and asphalt. When the bond is insufficient, this thermal cycling will break the bond and traffic break and remove the …

Helsinki Finite-State Technology (HFST) is a computer programming library and set of utilities for natural language processing with finite-state automata and finite-state transducers.

High Friction Surface Treatment (HFST) is an innovative technique to improve the safety of motorists at high-priority crash locations throughout the commonwealth.

Although the technology and material needed for High Friction Surface Treatment (HFST) have existed for decades, the benefits to drivers and overall road safety have only recently become …

A cost effective approach that has been shown to be effective in addressing high “friction demand” locations is the installation of a High Friction Surface Treatment (HFST).

HFST restores pavement surface friction characteristics where traffic has worn down existing pavement surface aggregates. HFST can also help compensate for inadequate geometric …

The High Friction Surface Treatment Association works with State and Federal Departments of Transportation and Public Works agencies to educate users on the life-saving benefits of …

The HFST resin binder material is a thermosetting, polymer-based material and is an 8 to 12 year friction-enhancing treatment. Other treatments such as microsurfacing and chip seals are …
