Seal coating is a maintenance procedure that consists of applying a thin layer of oil to the road and then immediately applying a layer of rock chips. The purpose of seal coating (sometimes referred to as “chip and seal”) seals small cracks in the pavement, protects the existing pavement from exposure to the elements that will deteriorate the pavement over a long period of time, and will provide a rougher surface to help prevent skidding, particularly in the winter months. After the seal coating operations have been completed, dust that was on the chips will become loose and get picked up by the tires of the vehicles. There will also be some chips that did not get completely adhere to the oil. For a period of time after the work has been completed the road surface will behave similar to a gravel road; however, over time, especially after some rain events, the dust and loose chips will be gone and the road will return to a condition similar to what it was prior to the construction. Typically, the County reseals roads every 10-12 years.
