This manual is intended for use early in a career in roadway and bridge maintenance and will assist in understanding the processes, methods, and materials for maintaining bridge and highway systems. The maintenance field is evolving into its own engineering science, a compbination of traditional civil engineering, industrial engineering, business management, materials science, industrial psychology, and environmental science. This guide is the first step in documentating that transition; this text will guide the development of engineering managers at the start of the 21st century. This version supersedes the Guide for Methods and Procedures in Contract Maintenance published in 1987.
