Abstract:
The paper discusses asphalt mixture design, its laboratory evaluation and highway pavement design methodologies used in Europe and the United States of America, California, with regard to fatigue resistance potential. A critique of several common practices, followed by recommendations based on the latest research findings and their relation to pavement field performance are included in the Introduction chapter. The paper presents particular data of fatigue resistance behavior measured on asphalt mixtures with various types of bituminous binder (neat, chemically modified and polymer-modified asphalt binders). These data demonstrate the differences between 50 {6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} loss modulus standard procedure and dissipated energy concept. Moreover, the variability of asphalt mixture fatigue resistance and the stochastic method for calculation of proportional coefficient as one of the pavement design parameters are presented. The implementation of such an approach may be used into a pavement design methodologies.
