Overview of Fine Milling in Road Maintenance
Fine milling, led by Josh Hornbeck, is a critical process in road maintenance aimed at removing deteriorated pavement, maintaining elevation, keying into existing pavement structures, and improving skid numbers. This involves texture adjustment, profile enhancement, and removal of rutting to ensure a good bond with existing pavements. Machine specifications, maintenance, and performance measurements are essential elements discussed in the detailed presentation.
