Rublization[1]​ (from English Rubblization) is a construction and engineering technique that consists of demolishing concrete in the same place where it is located and using it for new construction, rather than taking it to another location. This operation can result in time savings and a reduction in transportation costs. Rubbing is often used for two purposes: creating a foundation for new roads and decommissioning nuclear plants.

In road construction, spent Portland cement concrete can be broken down and used for a new surface, generally using asphalt concrete. Specialized equipment breaks the old layers of concrete into small pieces to form the base for the new concrete. This saves the expense of transporting the old pavement to a disposal site, and also saves on new material with which to construct the road base.[2]​ The result is a smoother surface than that obtained by a layer of asphalt that was applied over cement concrete pavement.[3]​ The technique has been used on highways since the late 1990s, and is also being used for cemented airport runways.[4]​.

Rubbing is a process that provides many benefits over other road rehabilitation methods, such as crack and seat or removal and replacement of a cement surface. The advantages would be: rubbing a concrete surface is 52% cheaper than removing it and replacing it with concrete; rublization reduces the road reconstruction time, from days of road closure to hours, provides great savings to contractors and reduces the environmental impact in the area; and rublization is a process that reduces carbon emissions and pollution.[5][6]​.

In the regulation of nuclear energy production, "Rublization" refers to a method of decommissioning a nuclear power plant. As with any technical dismantling, all building equipment is removed and surfaces are decontaminated. The difference is that all the structures located above, including the concrete containment building, are demolished, turning it into pebbles and burying it together with the foundation underground. The surface is then covered, filled and replanted for unrestricted use. This saves transportation and removal of the material, and creates additional coverage against radiation.[7]​.
