"You're seeing a number of new applications for tires." When they're low on tires, they either need to wait a few weeks to get more semi tires or mix in some consumer tires. Ouwinga shared that his suppliers grind the tires into a small mix using 1/4-inch to 5/16-inch chunks held together with urethane glue. "We've been having a little bit of a problem with truck tires," he said. They typically use semi tires, which don't have the nylon that consumer tires do. Ouwinga said he sometimes has to work around not having enough tires. Ouwinga company's $60,000 will go toward a washing system and tests of porous pavement technology. Like Ingham County, his company is one of several entities that were part of the $2 million EGLE grant announced in March. Those metal grates around trees can be a liability for tripping and a maintenance time-killer for cities, Clemens said. company, based in Grant, use truck tires to make porous surfaces like golf cart paths, driveways and rings around trees in cities. Tires also can't go into landfills as normal tires, Clemens added, because they could inflate with methane gas and rise to the surface, which causes problems for landfills.ĭave Ouwinga and his Porous Pave Inc. There are potential hazards from scrap tire piles, she said, that lead to mosquito breeding grounds, visual nuisances and fire risks. Other tires get small-scale reuses like playground equipment or as planters. Reusing tires has long been a goal and they are reused in a variety of ways: Some are burned for energy with special smoke scrubbers at landfills. "So there's a lot of tires," she said of the recycling possibilities. Kirsten Clemens, scrap tire coordinator for Michigan's Department of Environment, Great Lakes, and Energy, said Michigan residents go through about 10 million tires a year. Kutay said the surface can keep a dark black hue longer, and there's less noise and infirmities when the repurposed rubber is mixed properly. Keeping tires out of the landfill is the main reason to use rubber but there are other benefits to using their rubber for roads. When rubber-modified roads fail, it's usually a construction or mix problem and not the rubber itself, he said. "They want to see it long-term first."īased on his research, Kutay said experiments from the past decade or more are showing good techniques for producing mixes that can make quieter and longer lasting roads but may not be quite as good as other premium additives like polymers. "Typically our paving industry is slow to new things," he said. Emin Kutay, an engineering professor at Michigan State University who works on rubber-modified roads. Today's projects generally use rubber in the asphalt mix or rubber as a base and tend to be fairly small in scale, said M. Most big projects use federal funding and tire rubber is considered experimental and generally can’t be used on roads that get federal funding, said Kelly Jones, managing director of Ingham County’s roads department. The projects tend to be small and on local roads. Ingham County received a nearly $38,000 grant, enough to do about 750 feet of road built on top of a shredded tire base at Fitchburg and Parman roads near Leslie. State officials announced $2 million in grants last month for a variety of road projects using old tires.
