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.
Asphalt Rejuvenation Agent: Applying an oil based liquid to an existing road to replenish components of asphalt to help extend the life of the pavement.
Resurfacing and preventive pavement maintenance on various county and township roads.
