Abstract
The main purpose of this paper is to propose a procedure intended to improve the efficiency of the analytical road pavement design method, by employing the necessary courses according to the effective traffic volume, composition and axle load spectra on a road sector. The approach is based on measuring traffic data using a weigh-in-motion (WIM) system, for 36 months, on an important multilane highway in Romania. A designed application software was an essential traffic data processing tool. Pavement design was carried out using the Romanian standardised procedure, as well as using coefficients calculated with the employed software, based on collected traffic data. The latter represents the proposed design methodology, which led to a 15% reduction in asphalt thickness and a 10% thickness reduction for the stabilised course. The obtained results emphasised the technical, economic and environmental advantages of the proposed design approach.
