Blowout
A blowout is an extreme form of pothole that occurs when the base under the failure has completely failed, often leading the surrounding asphalt to "blow-out" along the edges.
Blowouts often require extensive base repair and/or reconstruction. Given the severity of the failure, it is crucial to ensure that root cause is identified and repaired along with the failed area. Often times these types of failures are "fixed" without root-cause being addressed, only to fail again.
These types of failures suggest an underlying lack of support within the base structure itself. These repairs often require complete base reconstruction, often with subgrade stabilization techniques to be applied, such as cement sub-grade stabilization and/or Geogrid placement.
