By using closed formed solutions, it is possible to calculate the response of multiple loads placed at random positions on a slab, thus overcoming the ESWL and pass-to-load repetition ratio concept for rigid pavements. This model overcomes the classical discrepancy between the Westergaard-Winkler (joints) model and the layered elastic Burmister model (no joints). Pavers® uses closed form integral solutions to model a concrete multi slab-on-grade as a classical Westergaard slab on a Pasternak foundation.

The interface between two adjacent layers can be varied between full friction to full slip using the BISAR or Van Cauwelaert’s WESLAY definition. The layers are isotropic except for the bottom layer where anisotropy is addressed by different moduli in the horizontal and vertical direction. Pavers ® contains a linear elastic multi layered model, which allows for the assessment and design of flexible pavement. Sound understanding of it’s basic principles and limitations is mandatory. The basis of any mechanistic pavement design method are the structural pavement models employed.

Hence, the effect of different pavement materials, strengths, load or complex load mixes can quickly be explored. It is a complete software package that allows the modern pavement engineer to define or use calibrated performance models and failure criteria for all pavement layers and subgrade in his pavement design and H/FWD assessment projects. The tool allows to back-calculate FWD-deflections, model the pavement structure, (re-)design the pavement, determine the load-carrying capacity (in terms of ACN/PCN), calculate the remaining pavement life and determine feasible rehabilitation measures. Pavers ® brings new efficiencies to the complex and demanding task of road, airport and industrial pavement design, construction, evaluation, and maintenance.
