摘要

After detecting a few cases of stripping of asphalt cement from the aggregate in bituminous pavement, there was concern in the Department that stripping might be a widespread problem in the state. It is agreed that water is the cause of stripping, and it was the opinion of some that pavements on granular bases would be less likely to strip because of supposedly better drainage characteristics. The purpose of this study was to investigate differently designed pavement structures in all areas of the state to determine if there is a correlation between base and pavement design and stripping. The results of this investigation showed that stripping was not as widespread as had been feared and that there was less stripping in full-depth bituminous base and pavement constructed over a lime-treated subgrade than in pavements constructed over granular bases. This was contrary to what some had theorized.
