This paper shows the influence which the differences in evaluating road traffic in urban and interurban areas on a European E-road in Romania have on the dimensioning of a non-rigid road pavement. In Romania, road pavement design is carried out using an analytical method, assuming the verification of three eligibility criteria. The first design stage is the traffic evaluation. The transformation of physical vehicles into standard vehicles is different for streets and for interurban roads. This leads to a differentiated classification of the two studied environments and to different traffic volumes. For this paper, we selected a study area set on the borderline separating the urban and interurban areas, on the European E60 road, in Romania. The pavement design was carried out using the standardised computer application called Calderom, which is based on the Burmister model for evaluating the state of stress and strain in the road structure under load. This paper shows the influence of the differences in evaluating road traffic, in urban and inter-urban areas on a European E-road in Romania, on the dimensions of a non-rigid road pavement.
