In order to solve the problem that traditional emulsified asphalt is prone to insufficient bonding between the cohesion wheels and layers under high temperature conditions, TE hard asphalt, SBS modified asphalt, 70# matrix asphalt and interface separator were used to prepare non-stick wheel emulsified asphalt, and the content of TE hard asphalt and different interface separators was determined by the test of sticking wheel rate and storage stability. The performance of self-made non-stick wheel emulsified asphalt and commercially available ordinary and SBS modified non-stick wheel emulsified asphalt passed the non-stick wheel rate test, composite shear and pull-out test and adhesion pull-out test were compared. The results showed that when the ratio of the three asphalts was 65% matrix asphalt + 20% SBS + 15% TE hard asphalt, the sticking rate and storage stability were the most balanced. When the content of A-type nanointerface separator was 3%, the effect of reducing the sticking ring rate was the most significant, from 0.78% to 0.31%, and the effect on storage stability was minimal. By comparing the performance of ordinary and SBS modified non-stick wheel emulsified asphalt with commercially available products, the shear and pull-out strength of self-made non-stick wheel emulsified asphalt at 25°C and 40°C were the highest, the temperature sensitivity was the lowest, and the interlayer bonding performance was the most stable. Therefore, self-made non-stick wheel emulsified asphalt can effectively improve the sticking wheel phenomenon during high-temperature construction process, improve the bonding strength between layers, and reduce the maintenance cost in the later stage.
