Dense Graded Sealcoat

A graded aggregate seal is a seal coating that uses a well-graded aggregate rolled into a high-float, emulsified asphalt, also known as a dense-graded seal. A typical gradation is 98% less than 16 mm, with 2%–7% passing the 75 mm sieve. Aggregate gradation determines the application rate of the emulsion.
