Terminology

Asphalt

A dark, highly viscous material composed mainly of petroleum; when refined and combined with aggregates and other fillers, it forms a cement-like substance used primarily for road and other hard surface construction. The most common form used is also referred to as “hot mix asphalt”.

Emulsified Asphalt

Long or short, paths of all sizes are an easy project or add-on.

Cold Asphalt Mix

A temporary material ideal for emergency patching projects as it can be applied in a wider range of weather conditions.

Crack Seal

An elastic, rubberized material applied to cracks to protect from moisture and prevent further asphalt deterioration including pot holes.

Fatigue Resistance

The ability of asphalt pavement to resist crack initiation caused by repeated flexing of the material.

Flexibility

The ability to conform to the settlement of foundation; generally enhanced by higher asphalt contents.

Impermeability

The ability of an asphalt surface to resist the passage of air and water into or through the pavement; generally decreases as a function of time and usage.

Pothole

Failure in the asphalt structure caused by water entering soil underneath asphalt, usually through cracks that have not been sealed, in an area that sees traffic.

Pavement Structure

The entire pavement system of selected materials from sub-grade to the surface.

Road Base

A crushed aggregate material used under asphalt installations to increase stability.

Seal Coat

The process of applying a liquid emulsion to an asphalt surface to protect it from the elements and delay the natural deterioration of the asphalt binder. In the simplest of terms, it is the equivalent of applying sunscreen to decrease the effects of sun exposure. As an aesthetic bonus, it restores the uniform color and appearance of new asphalt.

Slurry Seal

A thicker mixture of emulsified asphalt, fine aggregate, and mineral filler. This form of sealcoat is ideal for more deteriorated surfaces as a cost-effective alternative to asphalt overlay or replacement.

Tack Coat

A form of liquid asphalt or asphalt emulsion applied to an existing surface to promote bonding of new asphalt installation.
