THE BELGIAN ROAD RESEARCH CENTER'S OVERALL APPROACH TO ASPHALT PAVEMENT STRUCTURAL DESIGN
A structural design system for asphalt pavement, based upon the utilization of measured fundamental properties of materials, is presented. While the experimental methods for the determination of the fundamental properties of the materials are now well defined, they involve sophisticated tests which are not well adapted to everyday practical purposes (long time, high cost). For this reason predictive methods, based on numerous laboratory results obtained for the different kinds of materials, are made use of, mainly for bituminous mixes and granular materials. The different elements of design, namely, criteria for riding quality, loading conditions, stresses and strains in layered systems, fundamental properties of road materials and climatic factors are reviewed. Models for cracking and for rut depth are supplied. A field verification is reported. For the pavement design method itself, two approaches are presented. The first is a complete rational one, while the second is more approximative, but simpler than the first and, consequently, more practical. /Author/
