Preventing Stripping of Asphalt Pavements under Chip

2017-3-21  Stripping tends to occur under chip seals of urban curb-and-gutter streets because their closed structure traps water, which can damage asphalt where density is low. Results showed that using a more breathable fog seal instead of a heavier chip seal may help alleviate this problem. “The project was much needed to give maintenance personnel
