| 摘要： | This research attempted to solve the pothole repair problem through complete automation of a repair procedure. In The SHRP H107B research project, conceptual designs and feasibility tests led to fabrication of pothole repair equipment modules. This report describes how the modules were then computer controlled and mounted on a commercial truck chassis inside of a custom body shell. The fully automated system uses fewer laborers than manual pothole patching to reduce the cost of making repairs and to lessen the risk to the workers. A computer vision system and robot is shown to perform the repair operations under computer control. The system can cut and shape a pothole in asphalt surfaced pavement, vacuum clean the cavity, heat and dry the bonding surfaces and spray an asphalt emulsion and rock aggregate patch material into the hole. A flat and dense patch is created with no additional roller compaction, with average repair lifetimes expected to last several years using standard materials. Background information on pothole repair materials, procedures and economics is provided in appendices. |
