Abstract
A rigorous finite element model was developed to analyse a multi-layered pavement system with various material and geometric properties and to relate the surface deflections as measured to the computed values. Evidence of non-linearity and deviation from the classical linear elastic theory led to a more complex mathematical solution to fit the experimental data more accurately. The laboratory and field tests were compared with the computed values. The paper includes extensive discussion of these results and the conclusions drawn from them.

N2 - The Falling Weight Deflectometer (FWD) non-destructive testing technique has been used to monitor and assess the behaviour and performance of rigid pavement systems. In addition to the full scale site investigation, tests were also carried out with the aid of a specifically developed laboratory scaled model of the FWD.A rigorous finite element model was developed to analyse a multi-layered pavement system with various material and geometric properties and to relate the surface deflections as measured to the computed values. Evidence of non-linearity and deviation from the classical linear elastic theory led to a more complex mathematical solution to fit the experimental data more accurately. The laboratory and field tests were compared with the computed values. The paper includes extensive discussion of these results and the conclusions drawn from them.
