A Role of Innovative Construction Elements in Structural Design of Flexible Pavements
Original language description
The paper concerns performance evaluation of the pavements with built-in SAMI membranes and/or other grid-based reinforcing elements. The layered model of pavement mechanical behaviour is extended to account for mechanical response of built-in structuralelements via modification of the transfer conditions between layers. The shear mechanism of the soft membranes is used to model improper (partial) transfer of horizontal displacements and strains between layers and its primary use is to model SAMI membranes main function: prevention of transfer of adverse displacements and strains from the bottom (often deteriorated) part of the structure into the new overlay part. When modelling stiff reinforcing membranes, the tension stiffness of the grid-based reinforcement element enters the scene of transfer conditions and effects the transfer of shearing stresses and reduces pavement strains.
