Micro Surfacing Emulsion is a carefully designed mixture of polymer-modified asphalt emulsion, aggregate (small crushed rock), water, and additives, used to preserve and protect pavement surfaces by creating a new wearing surface.

Micro surfacing uses a polymer-modified asphalt emulsion that hardens chemically without relying solely on sun or heat evaporation, making it quicker to set and suitable for shaded or high-traffic areas. Slurry seal primarily depends on evaporation for curing.

1. 1. It extends pavement life by sealing cracks, improving surface friction, and correcting minor rutting. It also allows traffic to return shortly after application, usually within 1-2 hours.

Typically, roads with low to moderate distress, narrow cracks, no major rutting, and areas that require quick return to traffic are ideal candidates for micro surfacing.

Yes, it can be applied in multiple layers such as a leveling (scratch) course followed by a surface course. Each layer requires sufficient curing time before application of the next.

It is applied using specialized equipment like slurry trucks or continuous mixers that proportion and mix the components and then spread them uniformly over the pavement surface.

Typically between 1 to 2 hours under normal conditions, allowing roads to reopen quickly.

Micro surfacing can help seal cracks, but for wider cracks, crack sealing in advance is recommended to prevent water intrusion and reflective cracking.

Polymer modifiers and other chemical additives enhance early setting, durability, and bonding characteristics of the emulsion.
