CONTROL OF HOT MIX PRODUCTION BY COLD FEED ONLY

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. /FHWA/
