Load transfer at rigid pavement joints is a complex mechanism that can vary with concrete pavement temperature, age, moisture content, construction quality, magnitude and repetition of load, and type of joint. The FAA design procedure assumes 25 percent of the load applied to an edge of a slab is transferred at the joint to an adjacent unloaded slab. This effectively reduces the edge stress in the loaded slab by 25 percent compared to a free edge condition allowing fbr a reduced slab thickness. If the load transfer assumption is violated through a degradation of the joint system, the pavement life can be significantly reduced. The purpose of this study was to evaluate the load transfer effectiveness of several concrete pavement joint types by using nondestructive testing techniques. Several joint types and conditions that affect the efficiency of the joints were considered. Nondestructive field testing was conducted at four U.S. airports with a heavyweight deflectometer (HWD). Joint load transfer was found to be stochastic and not be adequately described by a single deterministic value. Probability distributions for the joint types and conditions were proposed. Based upon these probability distribution flinctions, the likelihood of observing mean values of load transfer less than 25 percent ranges from 60 to 100 percent, depending on the joint type and conditions.

The report discusses the evolutionary developments in mechanistic dowel behaviour theory proposed by Bradbury, Grinter, Friberg, Lessels, Timoshenko, and Westergaard. New findings relating to dowel bar behaviour obtained from finite-element modelling are discussed. A sampling of pavement performance model 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 summarised.

This synthesis report will be of special interest to pavement engineers and pavement construction and maintenance personnel responsible for portland cement concrete (PCC) pavement joints. Still pertinent information from NCHRP Synthesis 19 (1973), as well as new or updated information in the areas of joint design, construction, and maintenance are included. This report of the Transportation Research Board records the state of the practice with respect to the design, construction, and maintenance of PCC pavement joints. In addition, information on joint materials and sealing, the control of water on and in pavements, and the evaluation of pavement joint performance is provided.

This study was instituted primarily to develop techniques for assessing the load transfer efficiency of joints and cracks in rigid pavements using the Falling Weight Deflectometer (FWD) and to determine the factors influencing load transfer efficiency across such discontinuities. This report describes the evaluation of procedures for assessing the load transfer efficiency of transverse joints and cracks using FWD deflection data collected on a controlled jointed reinforced concrete pavement research facility in a laboratory study. The application of the procedures--on a number of jointed reinforced concrete pavement (JRCP) and continuously reinforced concrete pavement (CRCP) test sections on in-service rigid pavements, in order to determine their suitability for implementation in the field--is also discussed.

"This study evaluates fiber reinforced polymer (FRP) dowel bars as load transferring devices in jointed plain concrete pavement (JPCP) under HS25 static and fatigue loads and compares their response with JPCP consisting of steel dowels. Along with laboratory and field evaluations of JPCP with FRP and steel dowels, analytical modeling of dowel response was carried out in terms of maximum bending deflection, relative deflection (RD), and bearing stress of dowels. In addition, field rehabilitation of JPCP was carried out using FRP dowels to evaluate its long-term performance"--Technical report documentation page.
