Development and Evaluation of a Mechanized Pavement Patching Machine

摘要

This report looks at the state of the art in mechanized pothole patching. Initial evaluations were based on literature reviews and interviews with the personnel of various State highway departments. The objective of a single machine incorporating the various operations required for a fully mechanized pothole patcher appeared to be fully met by the Gabriel Perma-Patch machine. The equipment was then evaluated for performance and patch durability by the Colorado Dept. of Highways. Performance of the equipment was very good although being a prototype device, the perma-patch machine experienced several mechanical breakdowns. Patch durability was very good. No failures were observed in the patches placed during this study.
