PIQUA — In an effort to inform and educate city leaders on improved methods of redeveloping city streets, a special work session was held recently to discuss full-depth reclamation or FDR. A process or technique of pulverizing a street in need of repair – at a depth of 8 to 12 inches – and mixing the material with a variety of potential stabilizers for a uniform, more stabilized base.

“It’s a really, really great procedure,” said Doug Harter, director of the city street department, on the FDR process which has been around for well over twenty-plus years but typically utilized in the western portion of the country. Unfortunate given the many positives of utilizing the process, from energy and material conservation, to cost effectiveness, given there is no need to remove any of the old pavement.

After pulverizing the surface, stabilization consists of adding granule material before surface treatment which may consist of chip seal, double chip seal, cold mix overlay or a hot mix overlay.

Using the FDR method, Harter further stated, a whole street repair may take a week, whereas the old method or total reconstruction to fix problems such as potholes, rutting, and more, would take considerable funding and months.

Other benefits of FDR include a savings of 30 to 50 percent, as well as, benefits to the environment given the re-use of the original street material as opposed to hauling it away to the landfill.

Further, explained Harter, research shows that when done correctly it can last up to 20 years, “That’s pretty significant.”

Of course, the question on everyone’s minds, and as expressed by Mayor Lucy Fess, “Why have they not used it here?” with some of the obstacles being equipment. However, as stated by City Manager Gary Huff, there is no denying, “It’s a good option.”

Streets for FDR in the area will include Commerce Drive for this year, with Garnsey from Main to Roosevelt into 2015.
