Pavement preservation is key to longer pavement life and lower maintenance costs. Filling the cracks and potholes in a timely manner keeps water out of the asphalt base. Surface treatments such as sealcoating and chipsealing keep water from penetrating into the asphalt base, as well as reduces oxidation (deterioration) of the surface of the pavement. Unfortunately, asphalt deterioration is a snowball effect; the more the asphalt deteriorates, the faster it deteriorates.
Below is a chart that shows the quality (condition) of the pavement vs. the life of the pavement. Every time maintenance work is performed, we are able to extend the usable life of the pavement. The longer routine maintenance is put off, the shorter the usable life of the pavement and the more it costs to maintain.
