In road engineering a depression is a localised area of pavement surface that is slightly lower in elevation than the surrounding pavement.

Depressions are most easily identifyable after rain when they fill with water.

Treatment Options

Depressions can be corrected by applying a levelling course of asphalt to the depression prior to re-surfacing. This is known as Asphalt Regulation.
