Review and analysis of the variations in ageing rates of equivalent grade road bitumens based on colloidal structure Part 1: Critical review

From a performance point of view, bitumen is one of the most important constituents of asphalt mixtures. The quality and properties of bitumen depend largely on its chemical composition. Evidence obtained form laboratory oven ageing tests suggests that bitumens having the same grade, but originating form different crudes, can age quite differently. This evidence is further supported by data from laboratory compacted asphalt mixtures. The first part of this study reviews in some detail the effect of the chemical composition of penetration grade bitumens on ageing performance. Simple explanations of the ageing mechanisms are presented in the paper primarily based on chromatographic separation techniques. For the covering abstract see ITRD E145817
