Rout-and-seal or clean-and-seal? Which of these two pavement repairs is more cost-effective for your project? Recently a Minnesota company conducted a study on the longevity between the two methods for repairing asphalt pavement cracks. There are two techniques used to repair a crack in your pavement, clean-and-seal and rout-and-seal. While both are effective, which way makes the most sense for your financially?
The Minnesota Department of Transportation Research writes: “To review the performance of crack sealing, researchers evaluated the MnDOT construction logs of old repair sites and visited 11 new repair sites. These locations were revisited two, six, eight, 12 and 18 months following the repair. To calculate a performance index rating, researchers recorded data about site conditions that included sealant age, traffic level, subgrade soil type and crack sealing performance. Two sites were removed from the analysis when local crews applied chip seals to the pavements.”
