Assessing the stripping properties of granite aggregates in bituminousn mixtures

摘要

The properties of aggregates in asphalt pavements are an important influence on the service lives of pavements. Aggregates should be covered by bitumen film and the film should remain stable under the effects of water and traffic loads. We studied the stripping behavior of eight different types of granitic rock in bituminous mixtures. First, we conducted petrographic examinations and mineralogical and chemical analyses of the samples. Surface roughness and surface tension tests were then perform
