Abstract:
This paper describes the development of two computer-based procedures for the design of industrial pavements subject to heavy, off-road vehicles such as forklift and straddle carriers. The procedures model the subgrade as either a Winkler or a Boussinesq material. In either case, the methodology eschews the use of the equivalent wheel load concepts that have, hithertoo, formed the basis of most design methods for industrial pavements. Rather the programs seek to model realistically the wide spectrum of axle loads and axle configurations common in industrial applications. Such modelling requires large numbers of design calculations. For this reason the programs utilise methods of aralysiswhich have been developed to yield very compact computer code so that computation may be completed rapidly. This has the added benefit that the programs can run on relatively small computers including microcomputers. The programs are suited to the design of the jointed concrete pavements and of continuous pavements such as those formed from roller compacted concrete.
