Abstract In order to solve the problem of the decrease in abrasion resistance of SAP-pavement-concrete in seasonal frozen area, the effect of nano-SiO₂(NS) on the abrasion of SAP-pavement-concrete in seasonal frozen area was explored by abrasion resistance test. The pore structure and micromorphology variations of modified SAP-pavement-concrete by NS before and after freeze-thaw were analyzed by mercury intrusion pressure (MIP) and scanning electron microscopy (SEM). The enhancement mechanism of abrasion resistance was revealed from microscopic level. The relationship between pore size distribution and pore parameters with abrasion resistance were analyzed. The results show that after 150 freeze-thawing cycles, the abrasion amount of concrete modified by 3% NS decreases by 30.92% compared with JZ under 200 N load. Concurrently, there was an increase in the proportion of pores at the 20—50 nm, while the proportion of pores at 50—200 nm decreased. Additionally, total pore volume and porosity diminished, accompanied by a significant reduction in the number and size of interface cracks. Internal structure density was increased significantly,and the wear resistance was enhanced significantly.
