3 Aggregate Properties

aggregate is highly absorptive the aggregate continues to absorb asphalt after initial mixing at the plant until the mix cools down completely This process leaves less asphalt for bonding purposes therefore a more porous aggregate requires more asphalt than a less porous aggregate
