MICRO-SURFACING

Micro-surfacing is a preventative maintenance service to overlay oxidized asphalt using a mixture of dense-graded aggregate, polymer modified asphalt emulsion, water, mineral fillers and other additives. The polymer modified emulsion and other additives allow micro-surfacing to cure more quickly so it can be placed in greater depths  from 1/4” to 1/2” per pass.

Micro-surfacing is stronger and provides superior durability to slurry seal. The quick setting micro-surfacing emulsion allows traffic to return in about an hour.

Microsurfacing is typically available in two aggregate sizes. Type II uses a coarse aggregate and is used for all applications including roads, residential areas, highways and airports. Type III uses the coarsest aggregate and is used on higher traffic pavements, including freeways, high speed roads, industrial applications and runways.

SITE SELECTION

Pavement candidates may be asphalt or concrete pavements in good structural condition with low surface distress, raveling and minor rutting. It’s well suited for:

  • High traffic roads because its quick setting emulsions allow both quick traffic return and night construction.
  • Airport runways and taxiways because the high friction surface provides excellent skid resistance with no loose aggregates to damage engines or propellers.
  • Residential streets because of its deep black color that enhances the appeal of the neighborhood and a smooth surface that is conducive to biking and rollerblading.
