A chip seal, commonly referred to as a seal coat, is primarily made up of one size of aggregate that can be either washed or dusty. The aggregates can range in size from 19 mm to 4.75 mm. Generally, the largest particle should be no more than twice the diameter of the smallest one. Aggregate gradation and type dictate application rates for the aggregate and emulsions, as well as the type of emulsion.
