Study on the effect of acid rain erosion on the adhesion properties of asphalt-aggregate interface
Source abstract
Abstract
This study investigates the impact of acid rain on the adhesion properties of the asphalt-aggregate interface in asphalt mixtures. By employing surface-free energy theory and the sessile drop method to analyse wetting behaviour, the adhesion work and energy indicator ER were calculated. The interface adhesion characteristics were evaluated using the water boiling method and pull-off tests. It was found that acid rain significantly reduces the interface adhesion work, which worsens with increasing erosion cycles and concentrations. The ER value decreases, adhesion becomes poorer and the lower the pH value, the more severe the damage. The acidic environment accelerates the stripping of the asphalt film and weakens the interactive forces. Acid rain increases the polarity between asphalt and aggregates, reducing the adhesion energy and leading to failure. SBS-modified asphalt exhibits better adhesion performance than 70# petroleum asphalt.
