Milling, also known as pavement profiling, is a process which produces a smooth, uniform section of pavement. It is used to remove old worn-out pavement, adjust pavement height and facilitate better drainage which is essential for long pavement lifespan.
When complete pavement reconstruction is needed, both layers of pavement (the surface and the subgrade layer) will be removed through milling. The site will be inspected and prepared for entirely new asphalt. Edge milling is also utilized to ensure the new pavement properly bonds to the concrete curb.
