Viscoelastic Pavement Modeling with a Spreadsheet

Abstract

The aim herein was to equip civil engineers and students with an advanced pavement modeling tool that
is both easy to use and highly adaptive. To achieve this, a mathematical solution for a layered
viscoelastic half-space subjected to a moving load was developed and subsequently implemented in a
spreadsheet environment. The final program can consider up to five fully bonded layers, each isotropic,
homogeneous and weightless. The top layer (as well as others if desired) is linear viscoelastic, while the
remaining layers are linear elastic. The load is applied vertically to the surface of the system, uniformly
spread over a circle, and moving with constant speed along a straight line. The final workbook, named
ELLVA1, offers a near real-time solution for the history of stress, strain, and displacement inside the
system at any point of interest resulting from a single pass. Despite built-in formulation approximations
and limitations of operating under a spreadsheet environment, computation results are shown to be
almost exact.
