Abstract
Four Iowa DOT asphalt concrete pavement crack sealing projects were selected to evaluate the benefits of heat lance crack preparation. Two, one-half mile sections, both with and without heat lance preparation, were constructed in Story, Monroe, Clinton and Wayne Counties in 1991 and 1992. They were visually evaluated annually from 1992 through 1996. The heat lance preparation did not yield improved seal performance or extended longevity. There was no perceivable difference between crack sealing with and without heat lance preparation.
