Rapid Repair in Highway and Airfield Pavements

Controlled low-strength material (CLSM) is a highly flowable, self-compacting, cementitious material that is primarily used as a backfill in place of compacted earth fill. CLSM is often referred to by a number of different terms or types, including flowable fill, controlled density fill, flowable fly ash, unshrinkable fill, and soil-cement slurry. It is comprised of water, cement, fine and possibly coarse aggregates, and commonly contains fly ash or other industrial by-products, and chemical admixtures. The objective of this study is to evaluate current studies related to flowable fill, identify problems, lessons learned, and conduct research activities to make highway pavement repairs more rapid and inexpensive.
