摘要

The adsorption of a fatty diamine used in the manufacture of medium setting bituminous emulsions on both, bitumen droplets and different aggregates has been studied. The composition of the aggregates varied in different ratios of quartz, silicates and lime. The extent of adsorption of the diamine is increased with the fraction of silicates and decreased with the fraction of lime, with intermediate effect of quartz. The behavior of these aggregates in cold bituminous mixes varied strongly with the composition of the used aggregates. For instance, aggregates with lime predominant in their composition showed a complete covering by bitumen and, with quartz, a good covering. On the other hand, silicates lead to very poor covering of their surface by bitumen. The results of the adsorption isotherms and the empirical behavior of the cold bituminous mixes were correlated with the degree of destabilization of the bituminous emulsions produced by the desorption of surfactant from bitumen surface and adsorption on aggregate surface. Adsorption studies are a practical and useful method to predict the behavior of cold bituminous mixes.
