Project Description
The Utah Department of Transportation (UDOT) used FORTA-FI to reinforce 8.67 miles of highway on SR-31 to Junction SR-264 in Fairview Canyon, UT. This road used 14,117 lb of fiber and was laid at a thickness of 1.5”. Before the rehab, the pavement was experiencing many distresses including cracking, sub-grade soft spots, raveling, and shoulder fracturing. UDOT chose FORTA-FI to replace Stone-Matrix Asphalt and used a mill and fill to completely rehab this road that had previously gone 64 years with only chip seals and patching. The FORTA Voyager fiber feeder was used at the drum plant to combine the fiber with the asphalt mix. This is a high elevation canyon road with steep mountain grades and tight turns. The road is exposed to extreme temperature variations, freeze/thaw cycles, and heavy snowplow activity. UDOT chose FORTA-FI to extend the life of the road and get less cracking over the years and smaller cracks reflecting through the overlay.
Key Points
- Extend Pavement Life
- Reduced Cracking
- Reduced Raveling
