Pothole Repair & Paving
Asphalt patching is the processing of filling potholes in the asphalt pavement. Quick repair of potholes and surrounding pavement disintegration helps control deterioration and expensive repairs down the line. Without patching in a timely manner, water can enter the subgrade and cause more serious pavement failure. Full-depth or deep patch is a permanent pothole repair method, while a thin surface patch is temporary. Full-depth patching is the removal of the entire pavement surface, regardless of the thickness. Deep patching is the removal of 4 inches or more of the pavement surface. Full depth patching applies to either asphalt or concrete, but deep patching applies only to asphalt pavements. Materials for pavement patching include hot mix asphalt, asphalt emulsion mixes, stockpile patching mixes and propriety mixes with blends of aggregate and modified binders.
What Causes Parking Lot Potholes?
Business owners and property managers will have to eventually deal with potholes as part of parking lot maintenance. Potholes are caused by two main factors: water and high traffic. The winter and spring months are when we see the highest increase in new pothole formations, because of storms and freezing/refreezing ice. When it rains and snows in the cold winter months, water seeps into cracks & crevices of the pavement. The water freezes as the temperatures drop and expands, which forces the pavement to rise. The pavement is in a vulnerable stage; allowing potholes to form, because it is no longer able to support the weight it needs to and begins to sink.
You will not see the effects of this freeze-thaw cycle immediately; the pavement continues to weaken and eventually a shallow divot forms underneath the surface and the top layer of pavement will break.
