Abstract

To investigate the influence of aggregate chemical composition on the adhesion quality of the asphalt aggregate system, this paper designed a new sampling method by improving the micrometer, and selected three different types of aggregates with different lithologies to prepare asphalt aggregate samples, with drawing tests conducted in dry and immersed conditions. Meanwhile, it obtained the maximum load and work of fracture at the sample failure time by experiments, and calculated the delamination area of the failure interface by utilizing ImageJ software. Based on the one-factor analysis of variance, the correlation between rock chemical composition and water sensitivity was studied. The results indicate that the new sampling method can effectively control the asphalt film thickness in the drawing sample and promote adhesion failure at the interface between the aggregate and asphalt. For aggregates of different lithologies, mafic rocks have better resistance to water damage than felsic rocks. Analysis of rock chemical composition reveals that oxides such as Al2O3, Fe2O3, MnO, and MgO in the asphalt aggregate system can suppress water damage, while SiO2 can promote water damage.
