Asphalt Cold Planing in Memphis, TN
Controlled Removal of the Existing Pavement Surface to the Desired Depth
Cold Planing (CP) is the controlled removal of the surface of the existing pavement to the desired depth, with specially designed milling equipment, to restore the pavement surface to the specified grade and cross-slope. CP can be used to remove part or all of the existing pavement layers. The amount of material removed can also be varied in order to meet project-specific requirements. The resulting textured pavement can be used immediately as a driving surface. CP is more commonly used as surface preparation for one of the other rehabilitation techniques such as Hot In-Place Recycling (HIR), Cold In-Place Recycling (CIR), Full Depth Reclamation (FDR), or Hot Mix Asphalt (HMA) overlays.
The product of a CP operation is a crushed, somewhat “gap-graded” reclaimed asphalt pavement (RAP), which acts like an asphalt-coated granular material. The RAP can be used for hot recycling, Cold Central Plant Recycling (CCPR), or as a granular aggregate.
Pavement distress that can be treated by CP includes:
– Raveling
– Bleeding
– Shoulder drop-off
– Rutting
– Corrugations
– Shoving
– Removal of deteriorated, stripped, or aged asphalt
– Poor ride quality caused by swells, bumps, sags, and depressions
– Potential bonding problems between existing pavement and new hma overlay
– Diminished curb reveal heights
