Abstract:The steady increase in highway maintenance costs has emphasized the need for an extensive study of the entire maintenance problem. A definite demand exists for the immediate application of modern methods of bookkeeping, the use of up-dated equipment, and the utility of new and improved materials technology. In particular, the winter maintenance of flexible pavements calls for attention. The subject study deals with winter maintenance of flexible pavements and includes a review of the state-of-the-art. By use of field surveys covering materials, equipment, and techniques related to the maintenance of bituminous surfaces basic data were collected. Problem areas were revealed and recommended corrective procedures were outlined. This facet of the study covered eight districts or roughly one-third of the state system. Additionally, questionnaires were circulated to the rest of the state to gather information on problems and successful practices of the other districts.
