“What is this stuff?” is the second most common question at the National Garden at the United States Botanical Garden site, and the answer is "Gravelpave2". The Gravelpave2 pathways add a beautiful and porous surface to the grounds. The Architect of the Capitol wanted the sound and feel of gravel but needed ADA compliance for all visitors.
