In order to study the cementing durability of a newly developed epoxy modified silicone resin-SBR compound modified emulsified asphalt (EMSR-SCMEA) on the micro-surfacing aggregate, the long-term moisture damage resistance, long-term wear resistance and long-term anti-slide performance of the epoxy silicone resin modified emulsified asphalt micro-surfacing specimens under different wear times were studied. Results show these as follows. EMSR-SBR will increase the cohesion between asphalt and aggregate, and enhance the stability. The residual stability of EMSR-SCMEA micro-surfacing is better than that of SBR modified emulsified asphalt micro-surfacing, and the composite modification effect of 6% is the best. Under the same wear times, the mass loss rate of SBR modified emulsified asphalt micro-surfacing is much higher than that of EMSR-SCMEA micro-surfacing. The decay rate of swing value and structure depth at EMSR-SCMEA micro-surfacing is slower than that at SBR surfacing. After 20 000 times of accelerated loading, the decay of pendulum value and structure depth becomes stable.
