The floor of your plant is made of a different type, size, and gradation of material than your stockpile and if the bucket of the loader scrapes the ground, the the material in his bucket is being contaminated. It should be noted as well that the lower 2 ft of the stock pile can also be contamin ated...
ENGINEERING EVALUATION / FACT SHEET
Fine aggregate and coarse aggregate are brought to the asphalt plant stockpile area from the Kelly Mountain Quarry stone processing area on mostly graveled roads. RAP, asphaltic cement, No. 2 fuel oil, used oil and HMA are transported on the paved haulroad between the asphalt plant .
measurement of volume of aggregate in batching plant bin
Mobile batching plants are typically a single unit, made up of a cement silo, an aggregate bin, an aggregate conveyor and the cement and aggregate batchers, but at higher hourly production capacities may require numerous loads for a single plant. Typically, a mobile batching plant can be dismantled and reassembled in a few days time. Get price

Asphalt Concrete Questions Flashcards | Quizlet
More asphalt must be added to a mix containing porous aggregates to make up for that which is absorbed by the aggregates and is not available to serve as binder. True Slag, hard limestone, crushed concrete, and other manufactured aggregates can be highly porous, and that will decrease the asphalt cement quantity and cost of a mix.
Superpave Mix Design Pavement Interactive
Therefore, Superpave mix designs usually draw upon several different aggregate stockpiles and blend them together in a ratio that will produce an acceptable final blended gradation. It is quite common to find a Superpave mix design that uses 3 or 4 different aggregate stockpiles (Figure 1). Figure 1.
