Abstract:

The effect of asphalt concrete storage on asphalt cement properties and on the variability of gradation and asphalt content was determined. One mix stored in inert gas and 2 stored in normal atmospheres (all for 18 hours) were sampled before and after storage. In addition to these, 1 stored for 48 hours in an inert gas and another stored for 24 hours in a normal atmosphere were sampled solely to determine changes in asphalt cement properties. Four mixes were resampled from pavements after 1 year for further comparison of properties of asphalts from stored and control mixes. Properties of asphalt cement extracted from fine mixes were not altered by storage in either inert gas or normal atmospheres. Coarse mixes stored in normal atmospheres hardened significantly. For the 4 mixes resampled after 1 year in pavements, all initial similarities and differences were maintained. Gradation variability of all mixes, both fine and coarse, was increased by storage. Fine mix cores taken shortly after construction, however, show stored mix to be no more variable than mix directly from the pug mill.
