FEASIBILITY OF USING CONE PENETROMETER TRUCK (CPT) TO INSTALL TIME DOMAIN REFLECTOMETRY (TDR) AND FIBER OPTIC SLOPE FAILURE DETECTORS IN PAVEMENT (2011)
A new method of cable installation using a heavy-duty Cone Penetration Test (CPT) truck was developed and practiced successfully in this study. The coaxial and fiber optic cables were pushed along with the cone rods by the hydraulic system integrated with the CPT truck. A disposable tip—unable to carry tension along the axes of the rods—for the cone rods was designed and built to stay at the desired depth of installation holding the cables after the cone rods are pulled out.
