Interstate 81

Lackawanna County, PA - 2013

Project Description

Penn DOT District 4-0 placed the first interstate pavement using FORTA-FI® in the summer of 2013. A test section using fibers was incorporated into a stretch of 1-81 in Lackawanna County. Two separate two-inch sections of pavement were milled off and replaced with PG76- 22, one section with FORTA-FI® and one without fiber. The District is expecting long-term cost savings from the reinforced pavement.


In a follow up Field Performance Report done in 2015, the fiber reinforced sections outperformed the control sections with an average PCI rating of 94, labeled as “good”, while the section without fiber had a rating of 79 and was labeled as “satisfactory”. In 2017, the control vs. fiber sections were analyzed and the Field Report was updated. The fiber reinforced section still shows to have outperformed the control section with an average PCI rating of 82 (Satisfactory) and 65 (Fair), respectively.
