WisDOT regularly rubblizes portland cement concrete pavements prior to overlay with hot-mix asphalt. In this project, researchers sought to identify the factors that impact performance of rubblization projects. They found that HMA overlays of rubblized PCC in Wisconsin have matched or exceeded their design lives, with pavement structure age and overlay thickness being most the important variables affecting performance. Researchers developed a manual for designing and constructing rubblized PCC pavements that WisDOT can incorporate into its Facilities Development Manual.
