Research of Permanent Deformations of SMA 11 Mixtures with Different Gradations

Abstract

Gradation of mineral materials is regulated by corresponding part of EN 13108 and national specifications for bituminous mixtures, but it is up to contractors to develop long lasting asphalt mix within the limits of gradation curve and other empirical evaluations. The composition of mineral carcass has a significant impact on asphalt performance for empirical as well as fundamental characteristics (Haritonovs et al., 2005). This research establishes the correlation between empirical testing using Marshall method and fundamental evaluation of rutting using wheel tracking test (WTT)
