SOME ASPECTS OF THE COMPACTION OF ASPHALT MIXES AND ITS INFLUENCE ON MIX PROPERTIES (WITH DISCUSSION)

The quality of an asphalt pavement depends largely on the quality of the pavement construction. Asphalt mixes might be well designed and well produced, but when they are placed in the road in an improper way, the pavement performance will be poor. How poor has once more become clear in recent studies that have been carried out in the Netherlands. It was found that there is a clear relation between the degree of compaction and the asphalt mix properties (e.g., durability, dynamic resilient modulus, permanent deformation resistance). Descriptions of the compaction process were developed, based on field observations and theoretical analysis. These descriptions concern especially the dynamic equilibrium in the mix of the forces that are the result of the vapor pressure in the voids, the mortar viscosity and the roller pressure. This paper discusses findings of the Dutch studies concerning the importance of good compaction and the descriptions of the compaction process, that make the choice of the right roller at the right place easier.
