Crack Sealing Program

Crack Sealing, also knwn as Seal Coating, is one form of preventive paving maintenance that ensures a consistent operation of town roadways. Pavement cracks develope due to expansion and contraction cuased by temperature fluctuation. These cracks allow water to penetrate the pavement base and sub-base, causing pavement elements to lose structural integrity. Crack sealing is a hot-applied sealant which minimizes water penetration, and lengthens the life of the roadway by preventing early deterioration. 

Fog Seal

A fog seal is a light, blown-on ("fogged") application of a diluted slow-setting asphalt emulsion to the surface of an aged (oxidized) pavement surface. Fog seals are low-cost and are used to restore flexibility to an existing HMA pavement surface. They may be able to temporarily postpone the need for a surface treatment or non-structural overlay.
