Metal plates were also used as a control group for comparison. In addition, the researchers used a contact angle measuring instrument to investigate the coating effect of asphalt and aggregate at high and medium temperatures. The mechanical properties of the aggregate-asphalt-aggregate system under various adhesion conditions were comprehensively explored through dynamic shear rheology tests and direct tensile tests of the aggregate-asphalt interlayer. The results showed that the microscopic coating effect of asphalt and aggregate and the micro-roughness of the aggregate had a nuanced relationship. The basalt-asphalt interface was found to have good high-temperature properties, while the limestone-asphalt interface demonstrated optimal medium-temperature properties. Lastly, the granite-asphalt interface was found to have the best low-temperature crack resistance. interactions mechanical properties aggregate lithology interlayer thickness microroughness Full Text Cite Share Download PDF Status: Posted Version 1 posted You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
