Pavement milling is usually divided into three main categories. They include cement concrete pavement milling, asphalt cement concrete pavement milling, and bridge deck milling. The cement concrete pavement milling is the process of removing the old loose layers of the cement concrete and replace it with a new one.

Concrete milling is the process of removing the top layers of a concrete surface. It's carried out using scarifying machines equipped with diamond-tipped blades. Milling operations are effective at creating level, smooth surfaces that provide a lot of traction. Plus, the material that's chipped away can be repurposed for aggregate material ...

Milling also produces a rough, grooved surface, which will increase the existing pavement surface area when compared to an ungrooved surface. The surface area increase is dependent on the type, number, condition and spacing of cutting drum teeth but is typically in the range of 20 to 30 percent, which requires a corresponding increase in tack coat (20 to 30 percent more) when …

CONCRETE PAVEMENT SURFACE RESTORATION: DIAMOND GRINDING VS. CARBIDE MILLING. By design, most portland cement concrete (PCC) pavements last for 20-30 years, with minimal structural damage. The most common pavement deterioration after this time is increased roughness due to faulting, settlement, and wheel-path rutting due to studded tires.
