Rehabilitation of existing pavements is a top pavement priority facing transportation agencies. Hot-mix asphalt (HMA) overlays on asphalt pavements is an accepted option by all transportation agencies for restoring rideability, improving functional pavement performance, and increasing the structural capacity of the existing pavement system. HMA overlays can also be considered for application to an existing, deteriorated portland cement concrete (PCC) pavement providing measures are taken to eliminate reflection cracking emanating from the cracks and joints in the PCC pavement through the HMA overlay. One such measure is to rubblize the existing PCC pavement. This process was discussed in a two-part session on rubblization of portland cement concrete pavements at the 2005 Annual Meeting of the Transportation Research Board. The papers in this document were written following the session and are based on the presentations.
