Rehabilitating I-65 with a Sustainable Paving Interlayer
A section of Interstate 65 near Indianapolis, IN required resurfacing due to cracking from heavy traffic loading. The roadway included asphalt concrete layers over an underlying jointed concrete pavement. The project engineers originally considered a mill and fill operation to replace the deteriorated pavement with the same five inches of new asphalt concrete. Recognizing that using traditional replacement methods would yield short-term results, Indiana DOT (INDOT) looked for an option that would extend the lifetime performance of the road.
INDOT selected PETROMAT® Enviro™, a fully millable and recyclable AASHTO M288 Type II paving fabric interlayer containing no fiberglass.
