The North East Independent School District (NEISD), San Antonio, used Porous Pave XL to install ADA-compliant walking tracks at 44 elementary schools. Made in the U.S., Porous Pave XL is a porous paving material made with 50 percent recycled rubber chips and 50 percent aggregate mixed on site with a liquid binder. The 9-feet-wide, 675-feet-long, walking tracks provide an outdoor recreation resource for the schools and nearby neighborhoods.
