Patches
Original surface repaired with new asphalt patch material indicates a pavement defect or utility excavation which has been repaired. Patches with cracking, settlement or distortions indicate underlying causes still remain. Recycling or reconstruction are required when extensive patching shows distress.
Utility Repair - Typical repair of utility excavation -- patch in fair to good condition.
Edge Wedging - Pavement edges strengthened with wedges of asphalt -- patch is in very good condition.
Small Patch - Patch repairing small pothole -- in poor condition (cracked and spalled)
Potholes
Holes and loss of pavement material caused by traffic loading, fatigue and inadequate strength. Often combined with poor drainage. Repair by excavating or rebuilding localized potholes. Reconstruction required for extensive defects.
Small pothole where top course has broken away.
Large, isolated pothole, extends through base. Note adjacent alligator cracks which commonly deteriorate into potholes.
Multiple potholes show pavement failure, probably due to poor sub-grade soils and bad drainage.
