FACTORS AFFECTING LOAD TRANSFER ACROSS TRANSVERSE JOINTS IN JOINTED CONCRETE PAVEMENTS. IN: RECENT DEVELOPMENTS IN THE DESIGN AND SPECIFICATION OF CONCRETE PAVEMENT SYSTEMS (SP-181)

This paper presents preliminary results of a laboratory and a finite element investigation of the behavior of joints in jointed concrete pavement systems in terms of load transfer derived through aggregate interlock. The results have thus far revealed that aggregate type, texture and shape have a pronounced effect on the load transfer mechanism of an undoweled joint in a concrete pavement system. Pure aggregate interlock is not sufficient to provide adequate load transfer over a long period of time. The load transfer mechanism of an undoweled joint was modeled by a two-phase system (cement matrix and aggregates). This approach produced results that were confirmed by experimental results.
