• Abstract:
  This report is concerned with an analysis of the gradation control possible with recently improved aggregate cold feed systems. The gradation control for three mix types produced in a screenless batch plant was monitored and statistically compared with this state's historically documented control performance for batch plants with screens. The results indicate that with proper cold feed control a screenless plant operation can produce a more uniform mix than a batch plant with screens. Recommendations are given for improved screenless plant operations.
