THE APPLICATION OF SIMPLIFIED, FUNDAMENTAL DESIGN PROCEDURES FOR FLEXIBLE PAVEMENTS

Prior to acceptance in practice of complete analytically based pavement design procedures, engineers have to be introduced to the basic concepts involved and this can best be achieved by use of a simplified approach. The Simplified Design Method has been successfully used for such educational purposes and is described in detail. It makes use of charts and equations but has also been programmed onto a computer of modest size. The Analytical Design Method is a more versatile, but still somewhat approximate, design tool in the form of a computer program. The immediate use which can be made of a design package of this kind is demonstrated by investigating the effects of mix variables on layer thickness. /Author/
