Crack Seal

This is a form of street preservation consists of filling the cracks in the roadway surface with a rubberized crack sealant material. Since it is possible to drive on the crack sealant material immediately, no street closure is necessary.

Slurry seal

This form of street preservation consists of coating the surface of the existing pavement with a ¼ inch mixture of oil, emulsion, sand, water, cement, and fine aggregate. The streets being sealed will be closed to traffic for approximately 6 to 8 hours after the process is complete. Typically, the contractor will do entire subdivisions at one time and residents will be given 24 hour notice prior to the work beginning. The City uses slurry seal in lieu of chip and seal because it is much less dusty and rocky.

Mill and Overlay

This consists of milling the surface of the existing pavements and laying down a new asphalt surface. Typically this will replace the top 2 to 4 inches of asphalt pavement. Spot curb repairs and base repairs are sometimes included depending on the condition of the road. This process usually takes two weeks to complete. Residents will have access to their properties at all times except the day(s) when the surface is placed. The contractors are required to give 48 hours notice prior to placing the surface.

Reconstruction

This consists of removing and reconstructing all pavement, curbs, storm sewers, a portion of each driveway, and sidewalks (where applicable). See Reconstruction Process.
