Morton Arboretum Installs Crushed-Glass Porous Paving

The Morton Arboretum in Lisle, Illinois is testing a new porous pavement as part of a decades-long environmental commitment.

"We are constantly looking for more sustainable techniques and
products. This FilterPave porous pavement may be the way of the future," said Kris Bachtell, director of collections and facilities at the Morton.

About 90 percent of the FilterPave surface is recycled colored glass mixed with a an elastomeric binder, which the spec sheet says gives the pavement ?EUR??,,????'?????<

FilterPave is about 90-percent recycled colored glass mixed with an elastomeric binder. The glass is crushed, tumbled and rounded to a consistent 1/4-inch diameter. The base layer for the specialty paving is aggregate, crusher run limestone or equivalent with less than five percent fines. The wearing course aggregate is 1/4-inch to 1/8-inch angular crushed granite. The angular aggregate performs better than smooth rock aggregates. Images: Morton Arboretum

Only a handful of Chicago-area locations have installed this colorful paving material.

Emerald Site Services of Frankfort, Ill. donated the material and installation.
