The repair of the typical "pothole" or other similar small isolated section of structural failure. It involves removal and repair of the street section.
Bituminous or blacktop pavement by design is flexible to accommodate the freeze/thaw cycle of our climate. Subsequently, cracking will occur in relatively new pavement and continue throughout its life due to age, traffic, weather, etc. Crack sealing is the placement of a rubberized sealant in the crack that will provide a protective coating and seal out water.
The surface application of an asphalt emulsion followed by the placement of small graded aggregate. This coating is wear-resistant and protects pavements from oxidation and the effects of moisture.
Mill & Overlay
This process includes grinding the old surface to make the pavement uniform, then adding a new hot-mix overlay. An overlay is a structural improvement which renews the street surface and extends the life cycle of the original pavement.
All existing asphalt pavement is removed through a full-depth milling process, pulverized to a specific gradation, reclaimed and recycled with the existing aggregate base. Then a new full-depth hot-mix asphalt pavement is installed. It may also involve soil corrections and removal of aggregate base.
