摘要: A method is provided for repairing or preventing the faulting phenomenon in unreinforced concrete highways. Flowable, foamable, curable compositions are injected into the transverse joint between concrete slabs to fill any voids that exist between or under the slabs, and to fix loose incompressible "fines" which are forced beneath the slabs.
