Abstract The abrasion resistance of aggregates plays a decisive role in the anti-skid performance of asphalt pavement. The Los Angeles abrasion test (LA)was carried out to investigate the abrasion loss rate of the calcined bauxite, basalt and granite aggregates, and the variation of their morphological characteristics with the abrasion cycles. Moreover, the Pearson correlation coefficient was used to analyze the abrasion loss rate and morphological characteristics of the aggregates. Accordingly, the correlation model of the fractal dimension change rate and Vickers hardness of aggregates as a function of the abrasion loss rate was established. Further, the abrasion mechanism of aggregates was analyzed by means of SEM and XRD. As can be seen from the results, 88# calcined bauxite aggregates exhibit exceptionally superiority in abrasion resistance compared to 75# calcined bauxite, basalt and granite. Corundum and mullite constitute were the main abrasion-resistant components in 88# calcined. The established model is able to well describe the relationship of aggregate abrasion loss rate with fractal dimension change rate and Vickers-hardness. In conclusion, this research results provide a novel approach for improving and maintaining the anti-skid performance of pavement.
