Loading conditions in the triaxial test for the characterisation of the resistance to permanent deformation of asphalt mixtures : final report

Permanent deformation (rutting) is among the major causes of road maintenance costs in the Netherlands. Due to the sharp increase in truck traffic, introduction of new tyre concepts and European regulations, it is expected that permanent deformation might become more important in the near future than it is currently. By studying the permanent deformation characteristics of a pavement material and development of rutting prediction models one can set permanent deformation related specifications. These permanent deformation related specifications can be used by contractors and consultants tot control the degree of rutting.
