ANALYSIS, DESIGN, AND CONSTRUCTION OF TRANSVERSE JOINT LOAD TRANSFER SYSTEMS FOR RIGID PAVEMENTS. FINAL REPORT

The report discusses the evolutionary developments in mechanistic dowel behavior theory proposed by Bradbury, Grinter, Friberg, Lessels, Timoshenko, and Westergaard. New findings relating to dowel bar behavior obtained from finite-element modeling are discussed. A sampling of pavement performance models which use empirical or empirical-mechanistic statistical regressions to estimate load transfer performance (expressed as transverse joint faulting) in terms of material, environmental and traffic variables not considered by theoretical analysis is presented. The findings from a limited number of field performance and laboratory studies are summarized. Seventy years of design recommendations as inferred from theoretical developments, field performance observations and laboratory studies are reviewed. Recommended construction procedures associated with new rigid pavement transverse joint construction and transverse joint/load transfer restoration are presented. Joint related rigid pavement distresses are described. Finally, limited information concerning a proposed new load transfer system (X-FLEX (trademark)) under development at Kansas State University is presented.
