Micro-milling — also known as fine milling and surface planing — is one of the best ways to restore the age-old, oxidized asphalt pavements. It is considered a better alternative to standard milling, as it produces finer results. While traditional milling leaves the surfaces rough, micro-milling provides a smoother and plainer surface to work with.
