Chip Seal or Seal Coat is a thin surface treatment consisting of an application of liquid asphalt or emulsion binder covered with an aggregate. Seal Coat can be used to protect an oxidized or weathered surface by sealing the asphalt to prevent moisture from entering the pavement structure. Seal Coating is one of the industry's oldest and most proven surface treatments available. The entire operation can be conducted with the minimal traffic disruption.
Seal Coat Advantages
Binders
Polymer Modified Asphalt Binders
-
Most advanced binder for seal coats
-
Provides highest quality product with longest life and superior performance
-

Aggregates
Natural Aggregates
Gravel, Crushed Gravel, Crushed Stone and limestone are examples of natural aggregate that are available in 1/4" -3/4"
Precoated Aggregates
Precoating aggregate provides for a higher quality product. It maximizes the adhesion to the asphalt binder. It also helps in reducing the amount of dust that can be on the surface of the aggregate.
How is a Seal Coat applied?
-
The surface is cleaned of loose rock, vegetation and dust.
-
A liquid asphalt is applied by using a computerized, pressurized distributor.
-
Cover aggregate is applied by a means of a self-propelled chip spreader.
-
The surface is rolled by a rubber-tired roller.
-
Loose aggregate is swept of the surface.
A Seal Coat will not increase the strength of an existing pavement. However, it will prolong the life of a sound pavement by providing a protective coating.
