uniformity of asphalt concrete plant production

specializing in the production of large, medium and small concrete mixers, concrete mixing stations, stabilized soil mixing stations and other equipment. It is a heavy industry enterprise integrating R & production and sales.

Uniformity of Asphalt Concrete Plant Production

The average gradation from each plant was used as a base from which to compute uniformity. The differences between average gradations and individual sample gradations were analyzed statistically to obtain an indication of the uniformity of asphalt concrete production on a statewide basis. From this study it was concluded that: 1.
