Evaluation Of Anchor Grouting And Bearing Pad Materials For Use In Transmission Line Construction At Low Temperatures

In 1987, a laboratory investigation was undertaken to assess anchor grouting materials suitable for use at sub-freezing temperatures for the construction of transmission lines. Part of this investigation included carrying out field trials (i.e., rock anchor pullout tests) using the most promising grouts identified in the laboratory study. These pullout tests were conducted in May 1988, at a site near Lennox Thermal Generating Station. This report summarizes the rock drilling procedure and subsequent installation (grouting) of the anchor rods.
