STOPPING THAT OLD ROCK 'N ROLL : MUDJACKING

This article looks at the practice of sub-sealing, or mud-jacking, as it is known out in the field. When water seeps into a pavement slab, the movement of heavy vehicles on the slab creates hydraulic action which leads to the creation of voids, and ultimately, pavement failure. Voids are present when slabs begin to rock, new cracks start to appear, or residue appears at a pavement joint. Mud-jacking can be used to help forestall failure and avoid replacing the slab. The process involves drilling a 100-mm hole through the concrete slab, which is then followed by the forcing of a fly-ash slurry under the slab to fill the void. The article details the process at a site on Route 198 in California.
