In asphalt specifications, what does "AC" stand for?

In asphalt specifications, "AC" specifically stands for Asphalt Cement. This term is used to describe the binder used in asphalt mixtures, which acts as the glue that holds the aggregate particles together. Asphalt cement is a viscous black liquid derived from the refining of crude oil and is crucial in the production of asphalt concrete.

When referring to asphalt specifications, using the correct terminology is essential for clear communication among professionals in the industry. Asphalt cement is fundamental to the performance and durability of the final asphalt pavement. It is categorized by penetration, viscosity, and other properties that determine its suitability for different environmental and traffic conditions.

The other options, while related to asphalt and paving, do not accurately describe what "AC" stands for within the context of specifications. For instance, “Asphalt Concrete” refers to the finished product made from a mixture of asphalt cement and aggregates, while “Aged Cement” is not a standard term used in asphalt specifications. “Adhesive Compound” does not apply to asphalt at all and could refer to various types of adhesives in different contexts. Understanding the precise meaning of "AC" is essential for correct application in the field of asphalt paving.
