Load transfer across joints in concrete pavements through shear developed by interlocking aggregate was investigated in laboratory by simulating repetitive motion of tandem truck wheels across joint; effectiveness of load transfer was found to depend on load magnitude, number of repetitions, slab thickness, joint opening, subgrade bearing value, and aggregate angularity; "endurance index" is used to relate significant variables to test performance.
