A three stage validation process is described: the first two stages to be completed during its life and the final stage subsequent to March, 1993 as part of the ongoing Long Term Pavement Performance program. The first stage confirms that variation of asphalt binder properties identified as probable, significant determinants of pavement performance, yield physically reasonable, meaningful changes in relevant performance characteristics of asphalt-aggregate mixes. Details of the second stage validation are described including the direct correlation method and the indirect/mechanistic method. Post SHRP (Strategic Highway Research Program) third stage validation will offer the opportunity for refinement of those specifications through the LTPP Specification Pavement Study 9, Validation of Performance-Based Specifications and Mix Design and Analysis System.
