摘要：	The Americans with Disabilities Act (ADA) has established accessibility requirements for state and local government facilities, places of public accommodation and commercial facilities. Under the ADA, the Access Board has developed and maintains design guidelines known as the ADA Accessibility Guidelines (ADAAG). ADAAG establish minimum requirements for new construction and alterations, which primarily cover facilities on sites, but has added new provisions specific to public rights-of-way. The provisions include the installation of truncated domes on sidewalks at roadway intersections. The guidelines apply where a pedestrian route is altered as part of a planned project to improve existing public rights-of-way. This report summarizes a test program to document the durability of eight truncated dome systems under winter maintenance conditions of plowing and surface de-icing treatment.
