SIMULATION STUDY-BITUMINOUS CONCRETE PLANTS

THE BITUMINOUS CONCRETE PLANT WAS STUDIED AND VARIOUS METHODS OF MODELING THE PLANT WERE REVIEWED AND EVALUATED. THE MONTE CARLO SIMULATION TECHNIQUE WAS SELECTED AND APPLIED. A DIGITAL COMPUTER PROGRAM IN FROTRAN LANGUAGE WAS DEVELOPED WHICH MODELS THE AGGREGATE GRADATION PRODUCED BY THE PLANT. THE SIMULATION FIRST RANDOMLY SELECTS THE OPERATING CHARACTERISTICS OF A TYPICAL PLANT. THE AGGREGATE PRODUCTION IS THEN RANDOMLY GENERATED FOR THE OUTPUT OF EACH OF THE SEVERAL HOT BINS. THE TRUE GRADATION FOR EACH BATCH IS RECORDED TOGETHER WITH THE APPARENT GRADATION OF PERIODIC BATCHES AS OBTAINED FROM THE SIEVING OF SMALL SAMPLES. THE MODEL CAN BE USED TO APPLY DIFFERENT TESTING PROCEDURES AND SPECIFICATIONS AND STUDY THEIR EFFECT. THE TECHNIQUES EMPLOYED AND MANY OF THE BUILDING BLOCKS DEVELOPED ARE APPLICABLE TO OTHER BULK MATERIAL PROCESSES SUCH AS THE PORTLAND CEMENT CONCRETE PLANT. THE SIMULATION DESCRIBED IS A CONCEPTUAL MODEL BASED UPON LIMITED FIELD DATA IN NEW YORK. THE STATE OF NEW YORK HAS ADDITIONAL WORK IN PROGRESS THAT MAY BE USED TO FURTHER REFINE AND CALIBRATE THE MODEL. /AUTHOR/
