Hot-mix asphalt compaction is indispensable to ensure asphalt pavements durability, as has been shown by many studies in the past. Several types of rollers, mixtures and atmospheric conditions create a complex phenomenon for which there is not enough scientific and technical information. In this paper two different approaches to study this matter are assessed, with focus on its application field and advantages/disadvantages. The first approach consists in carrying out large field tests, where it is evaluated the influence of some variables in the compaction degree. The alternative approach consists in the up to date numerical modelling. In this study HMA is modelled in two dimensions and the material components (aggregate and bituminous mastic) are represented by circular rigid particles that interact with each other at soft contact points based on the Distinct Element Method.
