Load Transfer Characteristics of Aggregate Interlocking in Concrete Pavement
Publication: Journal of Transportation Engineering
Volume 136, Issue 3
Abstract
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 ” 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 . The numerical model, with the joint spring stiffness values selected from the present guidelines, has been validated with experimental results available in literature.
