FORTA-FI® - Dense Graded HMA
WYDOT had planned a 5” mill and fill along five miles of I-80 between Laramie and Cheyenne. In the Eastbound travel lane an existing longitudinal crack ran the length of the project. FORTA-FI® was added to the lower 2.5” lift of asphalt base course to slow the propagation of this crack to the surface.

After milling the pavement edges, a 2” FRAC overlay was placed on badly deteriorated 5th Street in downtown Casper. To address the need to control reflective cracking, FORTA-FI® reinforcement was chosen by the city in place of their standard 6 oz paving fabric for ease of installation and to avoid future problems with recycling.

Thurston County specied a 3” WMA section in two 1.5” lifts, both reinforced with FORTA-FI®. In the past, the use of conventional asphalt typically resulted in significant top-down fatigue cracking due to the intense car and truck traffic.

Thurston County specified a single lift 3” HMA section reinforced with FORTA-FI®. In the past, conventional asphalt typically resulted in the development of fatigue cracking due to high traffic volumes along this stretch of road.

The original design called for inclusion of a paving fabric to help delay reflective cracking. In the end though, an alternate FORTA-FI® design was used as it offers reinforcement throughout the full depth of the asphalt and better facilitates recycling of the road in the future.

Rehabilitation of the existing badly cracked road involved placement of a 1.5” thick FORTA-FI® reinforced HMA overlay. The City of Bremerton understood that conventional asphalt would last only 3 to 4 years before the existing cracks reflective through and a tight budget prevented them from carrying out more extensive treatment work.
