In 1942, as the nation plunged headlong into the second world war, the U.S. military opened the Dugway Proving Ground, an installation located 85 miles southwest of Salt Lake City, Utah, for the purpose of testing biological and chemical weapons in a low-drift, relatively contained area.

After a hiatus of several decades, Florida DOT once again is employing hot in-place recycling (HIR) with simultaneous hot mix asphalt overlay, this on U.S 41, the Tamiami Trail, a process known as repaving.

General background of the area Phoenix, Arizona, is located in the heart of Maricopa County. The head-quarters for the Maricopa County Department of Transportation (MCDOT) is located in the southwest portion of the city and has jurisdiction for all of the transportation routes for the unincorporated portions of the county.

Arizona would sound like the perfect place to do a hot-in-place recycling of asphalt rubber such as the one undertaken along 99th Avenue in Sun City, Arizona, last spring.

A major urban county in Florida is maximizing the value of its pavement management dollars by integrating scheduled pavement preservation.

You could say that Chandler, Arizona, is celebrating its tenth anniversary with hot in place Recycling (HIR) this year.

Scorched vegetation and contractor mistakes were among the reasons the City of Fort Worth stopped using hot-in-place recycling (HIR) as a pavement preservation process back in the 1990s. But now, in the 21st century, HIR has returned to the city’s “toolbox” of pavement preservation techniques.

A “green” hot in-place recycling (HIR) and repaving project in an environmentally sensitive area of south-central Colorado last year achieved 91 percent of its smoothness bonus for the contractor, even though the in-place process permitted the contractor only one pass to get it right.

Although Cutler Repaving Inc. sometimes finds resistance to its hot-in-place pavement recycling process, the company has a strong record of winning clients over after they try it, Vice President of Operations John Miles says. “We have customers that will never consider [using] anything else now,” he declares.

State Highway 150 is not the most heavily traveled road. In fact, its annual average daily traffic is less than 1,000 vehicles. But the Colorado Department of Transportation (CDOT) agreed to try a relatively new repaving method on 16.5 miles of the road where it leads into the Great Sand Dunes National Park.

A major urban county in Florida is maximizing the value of its pavement management dollars – while enhancing its program’s environmental sustainability – by utilizing hot in-place cling topped with a virgin lift of asphalt in one pass.

The City and County of Denver are both benefiting from a late-November 2007 tax increase which bolstered its streets program. As part of this Better Denver program, in addition to named capital projects, a maintenance fund was created to protect street infrastructure with preventive maintenance down the road.
