Why is cement mixing so easy?

The terms asphalt concrete, bituminous asphalt concrete, etc., are typically used only in engineering jargon. Asphalt pavements are often called just asphalt by laypersons who tend to associate the term concrete with portland cement concrete only. The engineering definition of concrete is any composite material composed of mineral aggregate stuck together with a binder, whether that binder is portland cement, asphalt or even epoxy. Informally, asphalt concrete is also referred to as "blacktop."
