Apr 20, 2018· In the BPN tester, the rubber of the pendulum friction meter mainly contacts with prominent coarse aggregates, so fine aggregates had little effect on BPN results. The coarse aggregates and asphalt content of these four mixtures was the same type of diabase, which contributed to similar BPN test results.

Home > Indicators > Slaking Slaking. What it is: Slaking is the breakdown of large, airdry soil aggregates (>25 mm) into smaller sized microaggregates (< mm) when they are suddenly immersed in water. Slaking occurs when aggregates are not strong enough to withstand internal stresses caused by rapid water uptake.
