High Friction Surface Treatment

Developing Alternatives to Traditional High Friction Surface Treatment Materials

For high friction surface treatments, Washington Mills offers their customers a wide range of highly durable brown aluminum oxide that can be used to reduce road traffic accidents by improving the condition of slick driving surfaces.

More specifically, Washington Mills offers DURALUM® HFST and DURALUM® HFST II, both of which are excellent and proven alternatives to traditional high friction surface treatment materials when combined with epoxy and spread over roadways. In fact, the successful application of these products for high friction surface treatment purposes has been verified by the National Center for Asphalt Technology (NCAT) and meet all AASHTO PP 79-14 specifications.

To ensure that asphalt material is completely resistant to skidding, these materials must be derived from high-quality, crushed and clean road surface aggregates that exhibit a low moisture content.

Furthermore, it is required that all road surface aggregates meet a series of quality specifications through required testing to qualify as an HFST material. Both the DURALUM® HFST & DURALUM® HFST II meet the AASHTO T 27, AASHTO T-96, AASHTO T 255, and ASTM C-25 requirements to be used as a road surface treatment.

High-quality, crushed, clean road surface aggregates, with low moisture content, are critical to anti-skid resistance. Road surface aggregates must go through thorough testing to meet a series of quality specifications and qualify as an HFST material.

DURALUM® HFST & DURALUM® HFST II meet AASHTO T 27, AASHTO T-96, AASHTO T 255, and ASTM C-25 requirements for use as a road surface treatment.
