• Abstract:
  Laboratory evaluations of asphaltic concrete mixtures are often used to measure the physical characteristics of paving materials. Laboratory materials evaluations and mix designs are considered a necessary part of the over-all job of building quality pavements. Since the results of such tests and evaluations may be affected to a measurable degree by certain aspects of the different testing procedures used, it is valuable and often necessary to know the extent of the effects of such factors. The test procedures of some state agencies require that hot-mix asphalt-aggregate mixtures designed and prepared in the laboratory be oven cured overnight at, say, 140°F in the loose state prior to molding and testing; while similar procedures followed by other agencies allow such mixtures to be mixed and molded without delay. It was the purpose of this study to measure the effect of oven curing on loose and compacted mixtures of asphaltic concrete made from dense graded aggregates and penetration grade asphalt cements.
