摘要

Field tests of sealing materials for random cracks and contraction joints in 3 concrete-lined canals are reviewed. Exposure periods vary from 2 to 10 yr; environments vary from a mild northern climate to a severe northern climate. Tests indicate that: (1) coal tar extended polysulfide sealants conforming to Bureau of Reclamation canal sealant specifications and the glass cloth reinforced asphalt mastic tape should provide a durable seal for random cracks; (2) the polysulfide sealant should provide durable sealing for contraction joints; (3) the rubberized asphalt mastic will be durable only if protected from the weather and if applied in a deep section; (4) application conditions are less critical for asphalt sealers than for synthetic rubber materials; and (5) the shape factor is a lesser consideration in joint sealers than in crack sealers.
