ESTIMATING LOAD TRANSFER FROM MEASURED JOINT EFFICIENCY IN CONCRETE PAVEMENTS

Relationships between joint efficiency and load transfer for jointed plain concrete pavements have been established using the finite-element method ILLISLAB program. Efforts were made to show that the relationship depends not only on "a/l" but also on "L/l", where "L" is the size of the square concrete slabs, "a" is the radius of the single-wheel load, and "l" is the radius of relative stiffness of the concrete slab. It is proposed that the relationship between joint efficiency and load transfer be developed based on "L/l" values. Four sets of curves were developed using "L/l" and for each set, the curves were separated for different ratios of "a/l". The procedure of equivalent single-wheel radius for multiple-wheel gear loads is discussed and recommended.
