Orlando and Orange Counties in Florida enjoy one of the best-kept road systems in the U.S. thanks to meticulous pavement preservation techniques and management. The rating is based on estimates of costs of annual vehicle wear and tear related to pavement. In those counties it amounts to $97 versus the national average of $396. At the top of the list was Los Angeles, with $706. Only 2% of the roads in the urbanized area of Orlando are rated poor, surpassed only by Atlanta and Phoenix. Nearly all of Orlando's streets are asphalt and the city has a goal of rejuvenating them all after six years, with an overlay or hot in-place recycling another 5 or 6 years after that. It is very systematic based on the pavement management system started in 1985. Orange County uses hot in-place recycling on many of its asphalt pavements, which number 2,538 centerline miles, one fourth of which are arterials. The distinctive, one-pass process reuses the existing deteriorated asphalt as a leveling course that is covered by a fresh layer of virgin hot-mix asphalt. A thermal bond is achieved between the recycled layer and the new layer, so there is no delamination. The heat from the repaving also creates a more durable, high-density seam with the adjoining lanes. A high-profile project on International Drive, in the heart of the tourist entertainment district, used the process because milling and filling would be too dusty and disruptive. The new pavement suppresses reflective cracking and eliminates dust in construct. Because it is a rolling process and trucks don't have to leave and enter the site, it causes less disruption.
