Some of the variables impacting unit costs are traffic accommodation requirements, roadway/street classification and configuration, material, method/procedures, documentation, performance evaluation and project size. There are a number of crack sealing, fog, sand, slurry, chip, cape, micro-surfacing and rejuvenators that can potentially be used to extend the life of the pavement by possibly addressing pavement distresses such as raveling and wear, minor rutting, cracking, flushing and polished aggregate.
