Abstract:
The bond quality between apvement layers significantly impacts pavement life. Poor overlay bonding may lead to delamination, slippage cracking, and premature fatigue cracking, reflection cracking, and rutting. There are several options to prepare the surfavce prior to an asphalt overlay. Choosing the right treatment depends on the existing surface condition and the type of overlay construction. This document gives guidance on when each option may be used and some information on bond strength testing and performance.
