This report is concerned with a study aimed at devising improved systems for rehabilitating heavily traveled urban expressways with a minimum of interference to traffic. The research included an extensive literature search and discussions with contractors, material supliers, equipment manufacturers, representatives fo state highway and transportation agencies, and others having information that could help in solving the many problems involved in reconditioning busy urban expressways. The end-product of the study is a series of detailed rehabilitiation schemes for several specific structural conditions. All of the schemes are designed to permit competion of construction activity on one-quarter-mile single-lane segments in 48 hours or less without total closure of the freeway to traffic and without significantly raising the elevation of the pavement surface. Some unconventional uses are made of normally available construction equipment and materials. /Author/
