categorized as either a batch plant (Figure 3-1), or a drum mix plant (Figure 3-2) and the information presented in this chapter covers these two types of plants. In the batch-type mixing plant, hot aggregate, recycled materials and binder are added in designated amounts to make up one batch. After mixing, the

Hot Mix Asphalt Plants - US EPA

The Plant D facility is a batch production plant with a normal production rate of about 150 tons/hr of hot mix asphalt. A realistic rate for a full production day is about 200 to 210 tons/hr. The facility air permit allows up to 255 tons/hr of production and is based on a production rate of 1 batch/min for 60 min.

1853 DETERMINATION OF THE ASPHALT BINDER CONTENT OF PLANT

1853.7 CALIBRATION USING HOT MIX ASPHALT (HMA) A. Prepare the mixture calibration sample at design asphalt content in accordance with Mn/DOT Laboratory Manual 1805 or 1820. When the sample is from plant mix, the correction factor for the actual % binder will be based upon a chemical extraction of the production mixture.

Hot Mix Asphalt (HMA) Quality Assurance

Job mix formulas are associated with a specific plant, which will be approved for an individual project. Therefore the start of a new project constitutes the beginning of a new set of LOT numbers. A calibration period for either a project or a job mix formula is not permitted. LOT numbers begin immediately with the production of the mixture.

EVALUATION OF HOT-MIX ASPHALT SAMPLING TECHNIQUES

Insuring the integrity and security of hot mix asphalt (HMA) samples is critical to assuring the quality of the installed product and complying with Federal requirements. Samples of HMA are often taken at the plant with limited state supervision. Further, samples are taken from a truck where obtaining a representative sample can be difficult.
