Porous Pathways Perk up Public Parks

Funded by a People for Parks grant from Broward County, Fla., Sunrise City's two new parks feature permeable pathways made partly from old tires.

Named a 2015 “Most Livable” City, Sunrise, Fla., strives to be a sustainable community. Public Works used a county grant to update pathways that retained mosquito-tantalizing rainwater.

Porous Pave is poured in place at thicknesses of 1 to 2 inches atop a compacted aggregate base of 2, 4, or 6 inches depending on application and required compressive strength. The City of Sunrise installed 2 inches on top of a 2-inch base of washed #57 limestone.

Made of recycled rubber, aggregate, and a binding agent, Porous Pave is engineered with 29% void space. Mixing time is less than a minute using a standard mortar mixer and curing time is 24 hours.

The pour-in-place mix conforms to any landscape design and installs on grades up to 30 degrees.
