Hawaii DOT Partners with FasTrac

The Hawaii Department of Transportation (HDOT) has announced that the pavement preservation project on the H-1 Freeway Waimalu Viaduct has been completed. The stretch of improved roadway includes a 1,300-foot stretch of the H-1 Freeway between the Kaahumanu Street overpass and Kaonohi Street overpass.

About the Project

To make the improvements, the contractor applied FasTrac CE330 Epoxy surface treatment across the freeway’s five eastbound lanes and seven westbound lanes including shoulders. The FasTrac epoxy surface treatment technique is the first to be used by HDOT, which incorporates a combination of epoxy binders and aggregates. It is designed to protect the freeway deck and underlying reinforcements, repair damaged spalled deck areas, and provide a uniform surface by covering old lane markings. The FasTrac surface has a higher frictional value than the current concrete deck which improves handling and breaking for vehicles and increases the service life of the structure.

“The H-1 Freeway between Pearl City and Halawa remains the most heavily used highway in the state,” said Hawaii Department of Transportation Deputy Director for Highways Ed Sniffen. “After we completed our H-1 Shoulder and PCCP Rehabilitation, we realized we could address the surrounding areas with a low-cost preservation solution that would improve the drive for years to come.

“We’re excited to have another tool for pavement preservation with minimal impact to highway users,” added Sniffen. “The epoxy treatment allows HDOT to protect and extend the life of our pavement surfaces. This will help us tremendously in improving the quality and speed of repairs to our roadways.”

The next location for the epoxy surface treatment is the H-1 Freeway in the Kaimuki area. This work is tentatively scheduled to begin by the end of September 2020. HDOT will notify the public of details when the schedule is finalized.

FasTrac 246 Concrete

FasTrac 246 Concrete is a is a one-component, shrinkage compensated, proprietary blend of cements, aggregates, and performance enhancing chemical additives. This rapid setting concrete is mixed with water on site, used for large- scale horizontal concrete repairs, and form and pour vertical applications that require high early-strength gain.

Where to use

Airport runways
Concrete slab replacement
Bridge deck repair
Parking decks
Horizontal concrete surfaces
Interior or exterior
Dowel Bar Retrofit

Features

Very rapid setting; allows structures to be opened to vehicular traffic in 3 hours
Non-gypsum based with volume stability
Excellent resistance to freeze/thaw
Shrinkage compensation minimizes cracking from drying shrinkage
Structural repair material
Low thermal profile

FasTrac CE330 Epoxy

FasTrac CE330 Epoxy Binder is a two-component, 100% solids, moisture-tolerant, high strength, low modulus, multi-purpose epoxy adhesive. It meets ASTM C881 and AASHTO M235, Type III, Classes B & C specificiations.

Use as a binder for High Friction Surface Treatment (HFST) on portland cement concrete, asphalt pavements and other approved substrates. CE330 is also used for bonding thin overlays on bridge and parking decks, as well as for bike and bus lane demarcation with colored aggregate.
