|Abstract:||Shear stresses at the interface between an existing concrete pavement and an overlay are calculated using the finite-element method for different loading conditions. The effects of vertical wheel loads, temperature loading, and wheel braking forces are considered. Perfect bonding between the overlay and the pavement is assumed. The results are checked against Cerrutti's closed-form solution in the case of horizontal wheel braking. The findings suggest that debonding in overlay construction in the field is likely to be caused by stress concentrations due to local defects. -from Authors|
