Rubblization is a cost-effective means of rehabilitating deteriorated portland cement concrete (PCC) pavements and is one of a series of "fractured slab" techniques that also includes "break and seat" and "crack and seat". In Rubblization the existing concrete pavement is broken into an aggregate base, and then it is overlaid with a designed thickness of asphalt concrete. These pavement rehabilitations are commonly designed to equal or exceed the design parameters for new pavements. This technique minimizes delays and allows for construction during off-peak hours. The rubblized roadbed is left in place and used as part of the new pavement structure. This not only saves landfill space and the costly construction necessary to dispose of wasted material, but uses the material for a beneficial and cost saving purpose.
