PURPOSES : The variability of hot bin aggregate weighing was evaluated through analysis of production data from three domestic asphalt batch plants. METHODS : Years of HMA production data that includes 94,362 batches from three HMA plants are analyzed for the study. Through the evaluation, the influencing factors of hot bin aggregate measurement variability were analyzed. RESULTS : The variability of hot bin aggregate weighing was found to vary greatly depending on the plant, and it was also found that the variability maintains a certain level regardless weighing amount in each hot bin. Also mixture type turns out to be the one of the major influencing factor that SMA showed the smallest variation in hot bin aggregate weighing, which imply the variability could be reduced by strengthening quality management effort. In addition, hot bin gate driving method did not show any significant effect on the variability while 2nd hot bin showed highest variability. CONCLUSIONS : Based on this analysis, problems with the current hot bin aggregate measurement standards were identified, and alternative criteria that could be improved were proposed.
