Type I  (#200x1/8") Fine aggregate mixtures are used for maximum crack penetration and sealing in low-density/low-wear traffic areas.

Type II (#200x1/4") General aggregates are the most commonly used and are widely employed where moderate-to-heavy traffic is found. They seal, correct moderate-to-severe raveling, oxidation and loss of matrix, and improve skid resistance.

Type III (#200x3/8")  Coarse aggregate corrects severe surface conditions - preventing hydroplaning and providing skid resistance under very heavy traffic loads.
