Clifton-Highline Canal Experimental Project No. I 70-1(14)33
This report describes the instrumentation and early performance of experimental pavement test sections on Mancos shale in western Colorado. The upper 26 inches of the pavement is the same for all the 33 test sections. Below 26 inches, the pavement designs or subgrade treatment are: four types of granular material, soil-lime subgrade, drilled-lime treatment to depth of 20 feet in subgrade, asphalt membrane on subgrade and overlain by sand or fine-grained soil layer, addition of moisture to subgrade both during and after compaction, and untreated (control). Instrumentation includes CHLOEprofilometer, Benkelman beam, curvature meter, rut depth gage, temperature potentiometer, roughometer, and nuclear moisture-density apparatus. Paving of the experimental project was completed in May 1965. PSI at time of pavement construction ranged from 3.4 to 4.4 for the various sections, with an average of 4.0. Although swelling has occurred in the subgrade of most of the sections, performance of all the test sections has been quite good. No specific conclusions can be drawn at this time regarding the comparable performance or value of the various treatments.
