Abstract

To enhance the overall mechanical properties and durability of asphalt pavement maintenance materials, this study proposed a high-performance asphalt pavement maintenance technology by designing a durable steel slag-epoxy ultra-thin wearing course (EA-UTWC ) with steel slag aggregate and epoxy asphalt binder. Comprehensive analysis was conducted on its fundamental mechanical properties, key pavement performance metrics, functional characteristics, and long-term durability. The experimental results demonstrate that steel slag aggregate significantly enhances the skid resistance, pavement performance, and durability of EA-UTWC. Specifically, the texture depth and high-temperature deformation resistance of steel slag EA-UTWC increase by 5.5% and 32%, respectively, compared to those of basalt-based EA-UTWC. Steel slag aggregate effectively strengthens the elastic response and suppresses viscous deformation of EA-UTWC, and a dynamic modulus of 7 377 MPa is achieved (32.8% higher than that in the case of basalt ). The superior deformation resistance of steel slag EA-UTWC delays fatigue damage accumulation, and its fatigue life is increased by 47.6% compared with that of basalt-based EA-UTWC. Furthermore, the EA-UTWC exhibits excellent volume stability, with no significant expansion observed after water immersion. This research provides novel insights for high-performance asphalt pavement maintenance technologies and helps promote the green and high-quality development of highway transportation infrastructure.
