STANDARD PRACTICE FOR MIXTURE CONDITIONING OF HOT MIX ASPHALT

MIXTURE CONDITIONING OF HOT MIX ASPHALT (HMA) Samples of HMA prepared in the laboratory have different properties from mixtures produced in a HMA plant for a number of reasons. One of these reasons is that the HMA ages as the mixture goes through the plant, and during storage and transportation, until the mixture cools down. The
