3.1 Definitions:
3.1.1 absorption, n—the increase in mass of aggregate due
to water penetrating into the pores of the particles, during a
prescribed period of time but not including water adhering to
the outside surface of the particles, expressed as percentage of
the dry mass.
3.1.2 oven-dry (OD), adj—related to aggregate particles,
the condition in which the aggregates have been dried by
heating in an oven at 110 6 5 °C for sufficient time to reach a
constant mass.
