In road maintenance projects, the asphalt emulsifier directly affects the performance of microsurfacing mixtures, the breaking and setting process, and the final pavement performance.

R5520 is a cationic slow-setting, fast-curing asphalt emulsifier, specially developed for microsurfacing, cold-mix cold-lay ultra-thin overlays, and other similar applications. It offers excellent emulsification performance and is compatible with a wide range of asphalt types.

R5520 provides a good balance between mixing time and setting speed. During construction, it maintains excellent workability of the mixture, helping ensure smooth spreading and paving operations. After spreading, it breaks and cures quickly, shortening the waiting time before opening the road to traffic and improving overall construction efficiency.

If you are looking for an asphalt emulsifier suitable for microsurfacing or cold-mix cold-lay ultra-thin overlays, we recommend R5520.

Storage Tips
