Applications of Asphalt Distributors

Asphalt distributors are used in a wide range of road construction and maintenance applications. Some of the most common uses include:

1. Tack Coat Application: A tack coat is a thin layer of asphalt emulsion applied to a prepared subgrade before paving. It creates a bond between the subgrade and the asphalt, improving the adhesion and durability of the pavement. Asphalt distributors are used to evenly spread the tack coat over the entire surface area.

2. Prime Coat Application: Prime coats are similar to tack coats but are applied to existing pavement surfaces to seal cracks and provide a smooth surface for overlay applications. Asphalt distributors are also used to apply prime coats.

3. Fog Seal Application: Fog seals are a light application of asphalt emulsion used to seal and protect pavement surfaces from moisture and oxidation. Asphalt distributors can be used to evenly apply fog seals over large areas.

4. Microsurfacing and Slurry Seal Applications: These are surface treatments that involve mixing asphalt emulsion with aggregate and applying them to existing pavement surfaces. Asphalt distributors are used to distribute the mixture evenly over the roadbed.
