The purpose of rubblization of concrete pavement prior to overlaying it is to produce a structurally sound base which prevents reflective cracking in the overlay by fracturing the concrete and then rolling it thereby obliterating the existing pavement distresses and eliminating future slab action. The MHB Badger Breaker® rubblizes up to 13 feet wide in a single pass.
Antigo refers to “modified rubblization” to describe the process of rubblization with the intent of producing somewhat larger particle sizes that compensate for a weak subgrade/base.

Guide to Concrete Overlays
This guide presents basic principles needed by pavement engineers for the design and construction of concrete overlays on existing asphalt, composite, and concrete pavements. See pages 105 and 107 for information on rubblization of concrete pavement prior to a concrete overlay.
