The bond quality between pavement 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 surface 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.
Poor bonding between asphalt pavement overlays and the substrate pavement layer can greatly influence the long term performance of hot mix asphalt (HM...
This test procedure is used to determine the bond strength characteristics of the interfacesbetween the surface of a stabilized base layer, prime coat...
