Below is a list of benefits, requirements, and procedures for asphalt overlays.
• Existing asphalt pavement needs to be in stable condition with no major repairs needed
• No sub-base (gravel underneath asphalt) replacement needed
• All potholes, alligatored asphalt, and depressions should be repaired prior to installation of the new surface
• Consideration of existing height of concrete, curbs, gutters, storm sewers, and walkways
• Check with village for asphalt overlay requirements and water drainage issues
• All necessary repairs should be completed to the existing pavement prior to installation.
• The asphalt pavement should be cleared of all debris
• Storm sewers and other in place objects may need “risers” to compensate for the increased height of the new pavement
• A tack coat should be applied to the old pavement to help with binding of the new pavement
• Asphalt will then be installed. Typically 1-2″ of asphalt are applied in an asphalt overlay
