PAVING THE WAY AT INDY

The Indianopolis Motor Speedway needed major repairs to the recurring problem of reflective cracking, the two main reasons for wich are the settlement of the track over the brick subsurface, and the stress of high speeds and heavy tires. The article describes how geotextiles were used to keep moisture out of paved surfaces and so help retard reflective cracking and extend the track's service life. Asphalt membrane interlayer systems were installed using two different pavement asphalt overlay fabrics to achieve high-quality rehabilitation on the high-speed curves and the pits area. Petrotac, a double-coated fabric was specified and installed on the curves. This consists of a nonwoven polypropylene geotextile precoated with rubberized asphalt cement on the bottom side and paving grade asphalt on top. The other paving membrane interlayer used was Petromat, a nonwoven polypropylene paving fabric. The installation of the fabrics is described, and the costs are discussed.
