Abstract:

The most comprehensive load transfer restoration experiment currently in service was constructed on Interstate 10 near Tallahassee, Florida, in 1986. The performance of this experiment has been monitored continuously by the University of Illinois and the Florida Department of Transportation between 1986 and 1992. Fourteen different load transfer restoration treatments were studied. Retrofit dowel factors studied included number of dowels per wheelpath, dowel length, and dowel diameter. Double-V shear device factors studied included core wall grooving and number of devices in the outer and inner wheelpaths. The results of condition surveys, faulting surveys, and falling weight deflectometer deflection load transfer testing of the project are reported. All of the treatments were effective in limiting faulting increases to much lower levels than the faulting increases of the control sections. In addition, they all improved deflection load transfer significantly, and after 5 years in service, deflection load transfer percentages are still similar to initial postconstruction values. The only poor aspect of the project's performance is slab cracking in the vicinity of many retrofit dowels, which appears to be the result of a combination of construction, materials, and climatic factors.
