The pavement management program was implemented in 1988. Committing to and continuing the preventive maintenance program is essential to delay the high costs associated with the deterioration of the streets to the point of major repair. Reclamite, sealcoating, mill and overlay, and route and seal are the four major methods used to extend the life of City streets. All four maintenance items are performed on a rotating basis dependent on need and schedule.
After paving, asphalt settles and dries out causing surface voids to form that allow water into the pavement and ultimately lead to cracking and other forms of pavement failure. Maltene-based pavement rejuvenation, using the product known as Reclamite, soaks into these voids to seal them. This process gives the asphalt more durability and flexibility, and results in longer pavement life.
Sealcoating has historically been the leading cost-effective technique for slowing the deterioration of our residential streets. The sealcoating process involves applying a thin coat of emulsified oil, and then covering with rock. The excess rock then is swept.
MILL AND OVERLAY
Mill and overlay is used for streets that are in the worst condition. These roadways have deteriorated past the point where sealcoating or Reclamite is effective. Mill and overlay consists of milling the top 2 inches of road and then overlaying with new asphalt. In 2015, the City implement a 6-year Accelerated Mill & Overlay program with the aim of repaving 85 miles of the City's 100 miles of residential streets.
ROUTE AND SEAL
Also called asphalt crack repair, this involves cutting existing cracks to a uniform size and filling with a hot rubberized sealant. This is performed to prevent water from entering the roadbed which causes damage during the freeze/thaw cycle
