Coarse Aggregate Specific Gravity – Pavement Interactive

Aggregate absorption is the increase in mass due to water in the pores of the material. Aggregate absorption is a useful quality because: High values can indicate non-durable aggregate. Absorption can indicate the amount of asphalt binder the aggregate will absorb. It is generally desirable to avoid highly absorptive aggregate in HMA.
