APPLICATION OF EXPERIMENTAL CRACK SEALING MATERIALS IN CONCRETE CANAL LINING -- ST. VRAIN SUPPLY CANAL -- COLORADO-BIG THOMPSON PROJECT -- LOWER COST CANAL LINING PROGRAM,
Abstract
Over the years many different materials and approaches have been used to seal the cracks and joints in concrete-lined canals. This series of tests was started to evaluate under service conditions some of the newer materials specifically for sealing cracks. Mastic joint sealing compounds conforming to Specifications for Sealing Compound, Rubberized, Cold Application, Readymixed, for Joints in Concrete Canal Lining, dated February 25, 1960, have been used for this purpose, and with considerable success. Test Sealer No. 21, a mastic conforming to this specification will be used as a standard for comparing the performance of the other materials. A few crack sealing materials were included in the tests started in the New York Canal, Boise Project, in 1956. The present test includes a larger variety and number of materials; also types of sealers not available in 1956 are being investigated in this series. This report covers only the application of materials in the new test; their performance in service will be described in later reports prepared after periodic field inspections. (Author)
