Public Works - Residential Street Resurfacing
The Village programs around $3,000,000 annually for the resurfacing of its residential streets. Streets are chosen from analysis of various input. The Village uses data from a street condition rating program. The Village also performs a visual inspection of pavements and investigates citizen inquiries. From this information a prioritized rehabilitation strategy is generated.
Resurfacing of street pavements is simply the placement of approximately 1½ to 2½ inches of asphalt over the existing pavement. Asphalt overlays are placed on both concrete and asphalt pavements. Preparation consists of various activities. Prior to the actual resurfacing, defective curb and gutter and pavement is removed and replaced. Old asphalt is typically milled off. Cracks in concrete streets are filled with an asphalt material. The road is then "primed" with a tack coat of asphalt that insures the new asphalt adheres to the existing pavement. Two lifts of asphalt are placed. The first lift, called a leveling course, helps to fill in any depressions in the road. Once this lift is in place, manhole castings are raised and then the final lift of asphalt is placed. On concrete streets the gutter is usually overlaid with asphalt. A resurfaced street can extend the life of the pavement for 20-25 years.
