Abstract: Aiming at the problem that the composition of broken pebbles is complex and its composition varies with particle size, based on the surface energy theory, the adhesion properties of asphalt and broken pebbles with different particle sizes were studied. The surface energy of asphalt and broken pebble was tested by sessile drop method and capillary rise method, and the adhesion work and peeling work of asphalt and broken pebble system were calculated. The comprehensive energy ratio (CER) was used to evaluate the adhesion properties of broken pebbles and asphalt in the four asphalt mixtures. The results show that the addition of anti-stripping agent will reduce the surface energy of the asphalt, increase the polar component, and reduce the dispersion component. Due to the different chemical composition, mineral composition and surface charge of broken pebble with different particle sizes, the surface energy of broken pebble with different particle sizes is different and the order from large to small is 5—10 mm, 10—15 mm, 3-5 mm, 0—3 mm. The adhesion work of 0—3 mm and 3—5 mm broken pebbles to SK90 asphalt, SBS modified asphalt,SK90 asphalt and SBS modified asphalt with anti stripping agent are better than that of 5—10 mm and 10—15 mm broken pebbles, and the peeling work of 0—3 mm and 5—10 mm broken pebbles to these four kinds of asphalt are less than that of 3—5 mm and 10—15 mm broken pebbles, which shows that the compatibility of different particle size broken pebbles and asphalt is different in adhesion perfor-mance. The results of water stability test of the mixture show that it is reasonable to evaluate the adhesion performance of broken pebble and asphalt with CER, and the size of CER can be used as the basis for selecting the material combination of asphalt aggregate system (especially the aggregate with complex composition),which provides theoretical and technical support for the application of broken pebbles in actual engineering.
