Asphalt milling that sets the next layer up to succeed.

Why milling is its own scope

Every overlay raises the pavement surface. After a couple of cycles, curbs lose their reveal, drainage stops reaching inlets and entrances develop a lip that catches bumpers and carts. Milling takes that height back out in a controlled pass so the new surface comes in at the original grade.

Standalone milling is also used on its own: to remove a delaminating or failed surface, to correct cross slope, or as a first phase while the paving scope is scheduled.

Depth, grade and cleanup

Commercial milling depths are commonly in the 1.5 to 2 inch range, set by the existing section, curb reveal and the thickness of the course that will replace it. The milling machine follows grade so the finished surface is uniform, and edges are feathered into curbs, inlets and stays-in-place transitions.

Some milled areas may carry controlled traffic after checking transitions, exposed structures, loose material and support. Other areas need closure until repaired or paved. Material removal, cleanup and recycling arrangements should be confirmed in the scope.

What milling exposes

Milling is also a diagnostic step. Areas where the base is soft or saturated show up clearly once the surface is off, and those areas are marked and repaired full depth before paving. An overlay over hidden base failure can develop recurring distress.
