A thin-surfaced pavement is either a single- or multiple-application bituminous surface treatment or a layer of hot-mix asphalt less than 50 mm (2 in.) thick over an unbound base. It is not an overlay of an existing hard-surfaced pavement. This synthesis reviews past and current practices for the structural design of these types of pavements. The factors reviewed include, but are not limited to traffic loads and volumes, environmental and climatic conditions (e.g., dust control, temperature, moisture), political reality and public concerns, life-cycle costs and first costs, material availability, performance characteristics, including service life, subgrades and drainage, use of recycled materials, material selection, construction practices, maintenance programs, and management of thin-surfaced pavements. |
