Asphalt pavement distress points accumulate as asphalt pavements age and traffic pounds them. If timely maintenance isn’t performed, distress points are compounded. Cracks become potholes and potholes become larger and larger holes as seasonal freeze/thaw, and normal traffic occurs.
Patching is the process of filling potholes or excavated areas in the asphalt pavement. Quick repair of potholes helps control further deterioration and expensive repair of the pavement. Without patching, water can enter the subgrade and cause larger and more serious pavement failures.
A full-depth or deep patch is considered a permanent repair, while a thin surface patch pothole repair is usually considered more temporary. Full-depth patching is the removal of the entire pavement over the patching area. Surface patching is simply cleaning the area to be patched of loose debris and placing new asphalt material in the void, and compacting the patch.
Q: How does the Metro District determine where and when potholes are scheduled to be patched?
A: The Streets and Roads crews constantly observe/evaluate the asphalt conditions specific to pothole repairs. These observations, along with input from the public, serve as the basis of scheduling pothole repairs. While virtually all potholes present some level of safety hazard, those potholes which constitute a clear and present danger to motorists on the roadways receive the attention of the Streets and Roads Dept first. Unfortunately, the age of many of the asphalt road surfaces throughout Pueblo West are nearing their functional life span. This condition adds to the high numbers of potholes that develop though the course of a year. Streets and Roads Dept crews strive to be as efficient and effective as possible in minimizing pothole road damage.
