Quality Assurance of Soil Nail Grout for Provo Canyon Reconstruction Project
In 2007, construction was completed on the most current segment of Provo Canyon reconstruction, US-189 Wildwood to Deer Creek, widening an 8 km stretch of existing 2-lane highway to 4-lanes. Many of the cut slopes throughout the project required either ground nail or tieback reinforcement. A neat cement grout, consisting of a 0.5 water-cement ratio (by weight), was used for both tieback and ground nail installation. The primary means of quality assurance of the cement grout, by specification, included random sampling of the wet grout for grout cube generation, and laboratory testing the compressive strength of the cubes at specified intervals of time. An alternative method was also adopted for quality assurance of the grout, measuring the specific gravity of the wet grout with a mud balance and drawing the potential compressive strength of the grout from specific gravity and compressive strength correlations. Periodic cube sampling of the grout was continued throughout to verify the strength correlations, and both test methods were evaluated simultaneously. The findings support utilizing both methods in conjunction with each other.
