Micro Surfacing

How is Micro-Surfacing Made and Applied?

Micro-Surfacing is made and applied to existing pavements by a special machine, which carries all components, mixes them on site, and spreads the mixture onto the road surface.

Materials are continuously and accurately measured, and then thoroughly combined in the Micro-Surfacing machine's mixer.

As the machine moves forward the mixture is continuously forced into a full-width "surfacing" box which spreads the Micro-Surfacing across the width of a traffic lane in a single pass. Or specially engineered "rut" boxes, designed to deliver the largest aggregate particles into the deepest part of the rut to give maximum stability in the wheel path, may be used. Edges of the Micro-Surfacing are automatically feathered.

The new surface ibegins as a dark brown color and changes to the finished black surface as the water is chemically ejected and the surface cures, permitting traffic within one hour, in most cases.

Continuous-load pavers use support units which bring the materials to the job site and load the machine while it is working, thus maximizing production and minimizing transverse joints.
