Surface Preparation – Pavement Interactive

After milling, pavement surfaces should be cleaned off (see Figure 2) before any overlay is placed otherwise dirt and dust may decrease bonding between the new overlay and the existing pavement. Milling also produces a rough, grooved surface, which will increase the existing pavement's surface area when compared to an ungrooved surface.

When the milling depth exceeds the expected threshold, it will affect the overall stability and structural strength, resulting in various forms of ...

Existing Surface Preparation for Overlays – Pavement ...

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 compared to an ...

Pavement milling - Wikipedia

MILLING &. PAVING. Pavement work is done in one of two ways: with a pavement overlay (also known as resurfacing) when the subgrade is in good shape or through complete pavement and subgrade reconstruction. Minor problems can be fixed through repair work but when pavement deteriorates beyond a certain point, it needs to be replaced.
