Park Protects Turf With
tons of crumb rubber were recently applied to one acre of new turf installed
at the Point State Park, Pittsburgh, PA. The crumb rubber was applied as
top dressing using a patented method and technology developed by Michigan
State University and marketed under the Crown III label by patent licensee
holder Jai Tire Inc., Denver, CO.
The crumb rubber was installed by
Dan Eichenlaub Landscaping Co. in a heavily used area of the park commonly
known as the "finish line area" where Pittsburgh's marathon, the Great
Race, and several charity walks end.
"The crumb rubber top dressing is
designed to protect the crowns of the grass and absorb some of the shock
and weight of the park's pedestrian traffic, " Eichenlaub said. In addition,
using crumb rubber as a top dressing has been shown to reduce the amount
of resodding required, thus reducing costs. Less watering is required and
it has been shown to provide a longer grass-growing season, Eichenlaub
AgRecycle, Inc., Cheswick, PA supplied
the crumb rubber which was prepared using a cryogenic process to freeze
size reduced tire chips and grind the embrittled chips into 3/8" fiber
and steel-free granules for use as top dressing or as an ingredient in
other products and applications.
The project is being financed by
a $50,000 state grant to the Western Pennsylvania Conservancy and is part
of a state Department of Environmental Protection initiative to promote
the use of scrap tires and scrap tire derived rubber in recreation sites.
Other recycling projects, such as making crowd-control fencing and signs
from recycled tire rubber, are being considered also.
"There's a bigger goal here," Eichenlaub
said. "This is an opportunity to use products that demonstrate that tires
have a viable use," he said.
