Clifton-Highline Canal Experimental Project No. I 70-1(14)33
The report is the third in a series describing the performance of the Clifton Project. This project was designed with the purpose of evaluating various treatments of the highly unstable subgrade located in the area. The treatments consist of subexcavation 2 feet deep, thin backfill, lime-treatment, asphalt membrane and the standard design. To date no major failures have occurred and no sections have been removed from test. However, in some areas throughout the project, pavement swelling and lineal cracking is taking place. This is usually an indication of the first signs of failure. Moisture analysis performed on the project indicate that, in all but those sections who subgrade is protected with an asphalt membrane, moisture has accumulated in the base course and precipitated onto the shale subgrade. This moisture is gradually penetrating the shale causing loss of support strength and swelling. As this moisture buildup continues pavement deflection, swelling and cracking will increase, pavement profile will deteriorate and subsequent failure will occur. Indications are now that failure will begin to be observed during the spring thaw of 1972. (BPR abstract)
