A Pennsylvania Department of Transportation (PennDOT) pilot paving program is testing a 3-in. lift of recycled asphalt paving (RAP) on two sections of roadway in Armstrong County.
The program is being conducted through PennDOT’s Road Maintenance and Preservation (Road MaP) initiative, which Gov. Tom Wolf recently said will invest $2.1 billion in roadway maintenance as well as highway and bridge capital projects over the next 10 years.
PennDOT will use RAP on 1.9 miles of Route 2018 (Campbell Run Road) and 3 miles of Route 2012 (Silvis Hollow Road). The department reports these roads were chosen based on their “poor” pavement-quality rating and proximity to the stockpile where the materials are stored. These roads also carry fewer than 3,000 vehicles each day on average, and trucks are less than 10% of the traffic.
PennDOTs estimates it will save roughly $146,000 using a 3-in. lift of RAP compared to 2 in. of new asphalt.
Last year PennDOT estimated it would cost more than $140 million just to repave the 375 miles of low-volume roads with rough pavements in Armstrong County. An additional $15 million will be invested in Armstrong County through the 2028-29 fiscal year due to Road MaP.
