Abstract
Abstract The problem of dimensioning pavements requires knowledge of the assumptions and calculation schemes underlying the assessment of deformations of pavements under traffic pressure. The aim of this paper is to study the influence of both the values chosen for the dynamics module of asphalt courses in the pavement and the elastic composition of the pavement using three bituminous layers (wearing, binder, base), or two bituminous layers (wear, binder/base). In the first part of the paper a general description of pavements is presented. Roads are also described, starting from Roman roads to modern roads. The characteristics of flexible pavements are highlighted and the dimensioning methods and specialised software for modelling and calculating these structures are presented. In this case study, the variation of the defining parameters in the design of pavements was investigated by varying the dynamic elastic modulus of bituminous courses and by varying the composition of the pavement by removing the binder course and the base course.
