VMA in a mix will typically drop when going from mix design to production. This is because there is more aggregate breakdown and dust generated in an asphalt plant relative to the mix design process. To help capture this important concept, think of the aggregate tumbling aggressively in a plant drum versus being stirred by a whip in a mixing bowl.
Jul 15, 2020 401.1 Design 401.1.1 Plant Mix Bituminous Base (PMBB) Course. Use of PMBB courses should be limited to bituminous bases beneath Plant Mix Bituminous Pavement (PMBP) surface mixtures on full depth light duty pavements, as base widening on routes designated as light duty corridors, or on any bypasses or temporary roadways, regardless of the corridor designation.

A control panel is for using/controlling the plant. Asphalt batch mix plant process. The process of asphalt batch mix plant is explained in details below. This equipment ...
During the plant trial, the mix looks dry, but the binder content and gradation are on target. This can be a very frustrating situation. Everything should be spot on, but the mix is just not right. If this were a high RAP (reclaimed asphalt pavement) mix the first thought would be that the RAP binder content is low, or the RAP amount was higher.
