A controlled foam injection (CFI) method has been developed, tested and demonstrated to have capabilities to fracture and strip reinforced concrete structures such as pavements and bridge decks. The method uses a high-pressure foam to initiate and propagate fractures in concrete structures. The breaker incorporates foam generating hardware capable of delivering pressures up to 100 MPa. Foams of various viscosities and stored energy can be formulated by varying the ratios of water, air,doi:10.1680/macr.188.8.131.52369 fatcat:culkvgv5abcxhhvf5al4r4q76y
