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.
Treated vs. Untreated Roadway
Benefits of DURALUM® HFST & DURALUM® HFST II Materials
- Manufactured in the United States
- When applied, these materials create a unique abrasion resistance for roadway surfaces
- Significantly reduces the incidences of vehicle crashes and related injuries as a result of slick surfaces
- Durable materials
- Long lasting materials prevent the need for constant repairs
- Reliable and consistent specifications are associated with these materials, all of which have been certified by a US-based manufacturer
DURALUM® HFST Applications
- High volume intersections
- Interchange ramps
- Traffic circles, rotaries, and roundabouts
- Road surfaces that freeze or become slick with water
High Friction Surface Treatment Testing Slab
DURALUM® HFST: A closely graded brown aluminum oxide material that has been manufactured and tested to meet all HFST specifications for roadway aggregate. This material exhibits a minimum Al2O3 content of 96%.
DURALUM® HFST II: A specially formulated brown aluminum oxide roadway aggregate material that exhibits highly desirable properties including hardness and abrasion resistance, all the while remaining chemically inert. This material exhibits a minimum Al2O3 content of 87%.
