what is micro surfacing of a road


Micro surfacing | Barnet Council

Micro surfacing treatment. Micro surfacing is a type of carriageway surface treatment used to prolong the life of a road by 10-15 years. The purpose is to seal the road surface by applying and rolling a layer of bituminous mix material as a new surface layer. This material will also correct surface texture and small undulations and cracks.

Slurry Seals vs. Microsurfacing – What's the Difference ...

Slurry relies on water evaporating from the asphalt emulsion. Microsurfacing doesn't need evaporation. The asphalt emulsion used in microsurfacing contains chemicals that allow it to break without relying on the sun or heat to cause evaporation. Microsurfacing, therefore, hardens quicker than slurry seals and can be used when weather ...
