Footprint Design Manual for Local Roads

This book examines design guidance available for resurfacing, restoration, and rehabilitation (RRR) projects. Resurfacing, restoration, and rehabilitation work includes placement of additional surface material and/or other work necessary to return an existing roadway, including shoulders, bridges, the roadside, and appurtenances, to a condition of structural and functional adequacy, according to the Code of Federal Regulations. Drawing primarily on case studies of current RRR practices and analyses of safety cost-effectiveness, Footprint Design Manual for Local Roads recommends practices that encompass the entire RRR process, but with a special focus on design. Engineering judgment based on local conditions is paramount in fulfilling the tasks to improve an existing roadway and to improve safety.
