Problem

The City of Oberlin needed to restore an existing asphalt pavement that was experiencing traverse, longitudinal, and alligator cracking due to traffic, and moisture getting into the pavement. Consistent with today’s state of the practice, a millable recyclable geosynthetic interlayer was required.

Solution

PETROMAT® EnviroTM was selected because it provides the moisture barrier and crack resistance benefits of the traditional Petromat interlayer, and it is specifically engineered to be easily milled and recycled back into new asphalt concrete. The designed elongation of Enviro makes it much more durable than brittle fiberglass-based products which lose much of their strength during installation, and it allows its placement directly on any pavement surface from milled to flat. The contractor chose Petromat Enviro for its ease of installation and because it was the most cost effective alternative for the City.

Performance

5,300 square yards of Enviro was installed under the new asphalt pavement. PETROMAT Enviro is equivalent in performance to an additional one and a half inches over overlay thickness.
