Each pavement surface has a unique structure, and is subjected to unique environmental conditions. Although roughly 98% of Village streets are asphalt, what lies below the asphalt surface can vary greatly from block to block. Each street,block, or portion of a block is subjected to different environmental conditions.
Flat or steeply sloped pavement, good or bad drainage, and the amount of tree canopy can make a big difference in the speed with which pavement deteriorates. With proper maintenance, asphalt streets can often last up to a century or more before complete reconstruction is needed.
Asphalt pavement will typically stay in what is considered "good" or "satisfactory" condition for the first five to ten years after resurfacing. Within two or three years after resurfacing, and again several years later, cracks in the pavement are filled with a rubberized asphalt compound. This seals the pavement, keeping water out and slowing deterioration.
Fair to Poor Condition
For the last five to ten years of a pavement's life, it typically drops into the "fair" or "poor" condition rating. At this point, preventative treatments like crack filling are not cost effective and are no longer used. Stop gap measures including surface patching and pothole patching, are performed on an as-needed basis until such time as the roadway is in need of another resurfacing.
