Abstract In order to study the influence of relative humidity on asphalt-aggregate adhesion, this work designs a macroscopic pull-out test and a microscopic test under four representative relative humidity conditions. The research results show that at the macroscopic scale, the pull-out force gradually decreases with the increase of relative humidity, and the cracking of asphalt-aggregate interface transitions from cohesive cracking to mixed cracking;at the microscopic scale, the cohesive energy of asphalt does not change significantly with relative humidity. The adhesive energy of asphalt-aggregate interface decrease with the increase of relative humidity. Therefore, the adhesion of asphalt-aggregate gradually decreases with the increase of relative humidity, and the increase of water vapor concentration can aggravate the displacement of asphalt by water molecules, making it easier for the asphalt to peel off the surface of the aggregate. Based on the macroscopic spalling rate and the microscopic surface energy parameters, an interface energy index was established. This index evaluates the adhesion of asphalt and aggregate at multiple scales. The evaluation results consistent with macro and micro tests indicate the effectiveness of interface energy indicators.
