This fifth and final report dealing with the design and construction of longitudinal joints in slip-formed concrete pavements presents a summary of findings from tests conducted at Chicago OHare International Airport. Tests performed include nondestructive tests performed with several types of vibrator and impulse loading devices, and loading with commercial aircraft. Pavement responses under the various loading conditions were measured using the geophones normally used with the NDT type equipment, and with deflection gages and strain meters installed in the pavement slabs. In these tests particular emphasis was placed on measuring the load transfer efficiency across transverse and longitudinal joints and the effect of load transfer efficiency on the behavior of the pavement system. Results from these tests clearly show the importance of load transfer on certain types of distress in concrete pavements, as loss of load transfer efficiency can lead directly to corner breaks and pavement faulting.
