Load Transfer Characteristics of Aggregate Interlocking in Concrete Pavement

This paper presents a finite-element model of a jointed concrete pavement with aggregate interlocking load transfer system. Interlocking mechanism has been modeled by a set of discrete springs. A new parameter “modulus of interlocking joint (Kj)” has been introduced to represent the load transfer characteristics of the interlocked joint. Guidelines have been proposed for the selection of the modulus of interlocking joint as a function of aggregate size and joint opening. Stiffness values for the linear springs can be selected using the modulus value Kj. The numerical model, with the joint spring stiffness values selected from the present guidelines, has been validated with experimental results available in literature.
