Improved Winter Pothole Patching State planning and research project no. 538 (Final)

摘要

This report is a summary of the findings from a literature search and survey to investigate winter pothole patching equipment and methods utilized by other state and local transportation agencies. An informal survey of nine transportation agencies was conducted to determine what types of specialized equipment were being used to perform pothole repairs. The results of the literature search and survey revealed that spray injection patching is a widely used and accepted method for pothole and related road repairs. There are three types of spray injection patching equipment: trailer type units, modified truck units and self-contained units. Four different manufacturers are currently producing this spray injection equipment in the United States. Each of the manufacturers was contacted and their equipment specifications and catalog information obtained. The equipment data is included as appendices in the report. Based on the information obtained from recent literature, other transportation agencies and equipment manufacturers, the spray injection process has been widely endorsed as an effective and efficient method for road repair.
