The city of Austin wrapped work on a sustainable sidewalk project that crews built using eco-friendly materials. The pilot ran along West 25th Street between Seton Avenue and Nueces Street in central Austin. The newly completed sidewalk comprises recycled tires, aggregate rock and a binding agent that is porous and flexible.
Austin partnered with Capitol Flexi-Pave on the project, with the more sustainable material designed to better protect trees in their âcritical root zone,â officials noted. âConcrete requires digging to set, limiting its application near trees as they would damage the roots,â the newsletter read, adding: âWhile concrete is impervious and no liquid can penetrate the material, Flexi-Paveâs permeability allows for water to flow through, providing better groundwater recharge protecting the roots.â
Leadership of the Virginia-based Capitol Flexi-Pave are degreed urban foresters who âspent years designing new ways to preserve trees in challenging urban settings,â Capitol Flexi-Pave said.
