The application of the dissipated energy method for assessing the performance of polymer-modified bituminous mixtures

Dissipated energy analysis has been adopted to assess the performance of bi tuminous mixtures with regard to their resistance to permanent deformation. The ranking given by the dissipated energy approach is in good agreement w ith the one obtained from the wheeltracking test. The dissipated energy ana lysis also provides a solution for the question which is posed by the conve ntional strain rate method, i.e. the exact determination of the end of the linear region in the curve of permanent strain versus number of cycles.
