To develop the potential of solid particles to maintain the storage stability of salt- and ice-resistant emulsified asphalt, nano-SiO₂ and nano-CaCO₃ without surface modification are mixed with emulsified asphalt with different antifreeze content. Through 10d delamination rate and 5d storage stability test, we studied the influence of two materials on the stability of salt-storage emulsified asphalt. The results show that the delamination settlement rate of salt-storage emulsified asphalt slows down with the increase of nano-CaCO₃ content, and first slows down and then accelerates with the increase of nano-SiO₂ content. The ability of nano-CaCO₃ to reduce the delamination sedimentation rate is higher than that of nano-SiO₂ at the same dosage. With the increase of nano CaCO₃ content, the 5d storage stability of lotion increases. Within 0.4% content, the storage stability of lotion increases greatly, and then the increase gradually decreases. Nano-CaCO₃ is more suitable as an additive stabilizer.
