FOURTH CYCLE OF PAVEMENT RESEARCH AT THE PENNSYLVANIA TRANSPORTATION RESEARCH FACILITY, VOLUME 4, RIGID PAVEMENT JOINT EVALUATION AND FULL DEPTH PATCH DESIGNS. FINAL REPORT

Many of the Interstate and other major highways in the United States wre constructed with jointed portland cement concrete (PCC) slabs. These pavements have provided good serviceability; however, the transverse joints of many of these pavements have deteriorated. This report discusses the research conducted at the Pennsylvania Transportation Research Facility that addressed the problem of PCC evaluation and full -depth repair procedures. A finite element program, JSLAB, was used in a parametric study to determine which variables have the most significant effect on the performance of transverse joints. It was concluded that the modulus of subgrade reaction, K, and the modulus of dowel/concrete interaction, G, have major effects on pavement behavior. The study showed that the deflection, measured at the slab corners under an 18-kip single axle load, can be used to predict K and G. Criteria of K equal to 200 PCI and G equal to 200,000 PCI were selected as limits for good joint performance. Evaluation charts were developed forjoint condition surveys. Field testing was performed on in-service pavements. An evaluation was also conducted on full -depth patch designs. The JSLAB finite element program was used to determine deflections of the patch system and loads transferred across the joint, and it was concluded that the inverted T patch design was not acceptable. It was also concluded that retrofit dowel bars should be 1 1/2 inches in diameter to reduce bearing stresses in the concrete.
