Abstract In order to improve the anti-skid performance of asphalt pavement,the aggregates were soaked in lithium silicate mixed solutions to improve the wear resistance in this work. The aggregates immersed in four kinds of lithium silicate mixed solutions with five different mass ratios were prepared and then initially selected by water immersion test and photoelectric colorimetric test, and then re-selected by Los Angeles abrasion test and polishing value test. The properties of selected aggregates was evaluated by crushing value test and density and water absorption test, and improvement mechanism of the wear resistance of soaked aggregates was explored through infrared spectroscopy test, scanning electron microscope, and AIMS aggregates image measurement system. The results showed that the adhesion and abrasion resistance of the aggregates soaked in the mixed solution of lithium silicate and silicone-acrylic emulsion with a mass ratio of 6∶4 were good, and its adhesion had reached the fifth level, and the abrasion loss had been reduced by about 25%. Solution immersion had little effect on the apparent relative density of the aggregates, but it obviously reduced the water absorption of the aggregates, and improved the crush resistance of the aggregates. The mixed solution of lithium silicate and silicone acrylic emulsion had chemical bond with limestone, which made the mixed solution better adhered to the aggregate surface. Because lithium silicate also had good wear resistance,so the protective layer formed by the mixed solution of lithium silicate and silico-nacrylic emulsion around the aggregate delayed the attenuation of aggregate angularity and surface texture, and improved the ability of aggregate to maintain angularity and surface roughness, so as to improve the wear resistance of aggregate.

Key words： lithium silicate mixed solution limestone silicone acrylic emulsion
