A slurry seal is composed of asphaltic emulsion (oil and water) and aggregates applied on top of the existing pavement surface at an average thickness of 1/8 to 1/4 inch. The slurry mixture seals the pavement from water intrusion, which is the leading cause of deterioration of a street. By regularly sealing the street, the City can extend the life of the streets in better condition, to prevent these streets from dropping into more expensive repair categories. The most cost-effective pavement maintenance programs use slurry seals to keep good pavements in good condition.
