Glossary of Terms:

Pavement Planing:  Grinding or milling of asphalt surfaces to remove existing asphalt surface in preparation for a new asphalt (blacktop) surface.

Stress Absorbing Membrane Interlayer (SAMI): A polymer modified liquid asphalt product applied to an existing surface to control cracking before an asphalt overlay.

Pavement Repair:  Spot removal and replacement of damaged pavement.

Paving:  Generally an asphalt (blacktop) overlay.

Chip and Seal:  A layer of stone aggregate (chips) over a coat of liquid asphalt emulsion tar (seal).  Done as an intermediate step before an asphalt overlay in order to seal cracks in existing pavement before the overlay, or as a final surface course.

Microsurfacing:  A mixture of asphalt and other mineral fillers that is applied in liquid form to existing pavement surfaces.  Seals cracks and provides a hard surface.  Requires closure of the road for approximately 2 hour.

Full Depth Reclamation:  Reconstruction of a road base by pulverization and stabilization, followed by a new asphalt and/or chip seal surface.  Requires closure of the road to through traffic for 7-10 days with local traffic maintained.

Slurry Seal:  Similar to microsurfacing but with a different combination of liquid asphalt and mineral fillers.  Generally used for low traffic streets.  Requires closure of the street for approximately 4 hours.
