A STUDY OF FIELD PERFORMANCE OF AN EXPERIMENTAL PORTLAND CEMENT CONCRETE PAVEMENT
An experimental section of P.C.C. pavement on U.S. 23 in Ross County, Ohio is studied. Variables included in the study are: (1) Joint spacing; (2) Sub-base stabilization; (3) Coating of dowel bars; (4) Configuration of the saw cut; and (5) The use of skewed joints. The yearly curve of joint movement is plotted from hand gage readings. Electronic instrumentation is used to give a continuous record of daily horizontal slab movements. Deflection of the slab ends under known axle loads is measured. A complete record to date is given of the progress of mid slab cracking. Spalling at the bottom of the pavement is measured and plotted for each of the 101 contraction joints in the project.
- Study conducted in cooperation with FHWA.
