Compaction | Washington Asphalt Pavement Association

This is done by reporting density as: Percentage of TMD (or "percent Rice"). The expression of density is easy to convert to air voids because any volume that is not asphalt binder or aggregate is assumed to be air. For example, a density reported as 93 percent Rice means that there are 7 percent air voids ( – 93% = 7%).

Asphalt - Wikipedia

Asphalt, also known as bitumen (UK: / ˈ b ɪ tj ʊ m ɪ n /, US: / b ɪ ˈ tj uː m ə n, b aɪ-/), is a sticky, black, highly viscous liquid or semi-solid form of petroleum.It may be found in natural deposits or may be a refined product, and is classed as a pitch.Before the 20th century, the term asphaltum was also used. The word is derived from the Ancient Greek ἄσφαλτος ásphaltos.
