• Abstract:
  The Virginia Department of Transportation has been working to replace traditional asphalt concrete specifications with end result specifications since the mid 1960s. The type of end result specification that is most possible is the performance-related specification where product quality characteristics and life-cycle cost relationships are correlated with performance. The development of tests for quality characteristics and the development of reliable life-cycle cost relationships present challenges. The identified asphalt concrete quality characteristics were degree of compaction, thickness, smoothness, segregation, strength, and durability. Each characteristic is discussed, and an estimate is given with regard to when each characteristic could be used in a specification. It was estimated that a performance-related specification for asphalt concrete may be possible in Virginia by the year 2005.
