The effect of prolonged hot storage of the elastomeric PMBs on the rutting and fatigue properties of hot mix asphalt

The aim of the present study is to identify the changes in the physical and rheological properties of an SBS modified binder under prolonged hot storage and analyse the impact of these changes on the performance of a dense graded asphalt mix prepared with the aged modified binder. In order to achieve that, laboratory performance related testing is employed. The tests used in the investigation are: dynamic creep (MATTA), fatigue test (beam fatigue apparatus), wheel-tracking test (Cooper technology wheel-tracker). The study found that despite changes in some of the rheological properties such as consistency, underlying viscosity, softening point, torsional recovery and stiffness, the rutting and fatigue resistance remained unchanged. This would indicate that the performance of the hot mix used in the field using the aged binder is unlikely to change. (a) For the covering record of the conference, please refer to ITRD no.
