Parking Lot Maintenance

Asphalt Removal and Replacement

The asphalt perimeter area will be saw cut to insure proper match joints with the existing asphalt mat. The old deteriorated asphalt is removed and hauled off site. The sub base is inspected for structural integrity. If sound it is compacted or replaced and compacted if inadequate. A new asphalt mat is installed and compacted at the specified thickness.

Asphalt Resurfacing

This is commonly known as an “Overlay”. Depending on your parking lot topography, condition of existing asphalt, sub base and sub grade this is an economical alternative to a complete replacement. Our experienced estimators will consult with you on the pros and cons, and what can be expected from this type of repair. SEE OVERLAY FAQ.

Strom Drain and Catch Basin

Norwest Blacktop offers either a repair or rebuild option. The asphalt perimeter area will be saw cut to insure proper match joints with the existing asphalt mat. The area will be excavated and the debris hauled off site. In a repair, we will then remover the decayed blocks, rebuild and cement all joints. New crushed aggregate is back filed and compacted. The existing cast iron grate will be reinstalled and adjusted to proper grade elevation. A new asphalt mat is then installed. In a rebuild, the same procedure is followed with the exception that a pre-cast concrete catch basin is installed and tied into the existing drainage lines.

Asphalt Pothole Repair

Potholes will be cleared of debris and filled with hot mix asphalt or cold patch asphalt then compacted to match existing asphalt surface.

Infrared Repair

Existing asphalt mat is heated through then the oxidized surface material is raked and removed. New hot mix asphalt is then raked, graded into place and compacted to match existing asphalt surface.

Cracksealing

Norwest Blacktop offers three types of cracksealing, routing, wire wheel cleaned or cleaned with compressed air or mechanical blowers. Depending on the width and type of crack (Longitudinal, Expansion or Alligator), Norwest Blacktop will consult with you on budget, and longevity of repair desired. Once determined Norwest Blacktop will then clear cracks of all dirt, debris and vegetation. A premium construction grade hot rubberized tar, designed to meet ASTM specifications for Municipal and Commercial parking lots to minimize tracking and pickup from pedestrian foot traffic is poured into the cracks.
