Pavement performance, defined as the trend of PSI (present serviceability index) with increasing axle applications, was found to be functionally related at the AASHO Road Test to stressed and deisplacements. The well known Boussinesq solution was used in the determination of stresses and normalized deflections. A more sophisticated (although not necessarily more correct) multi-layer theory was found to be no more useful than the simple Boussinesq solution in determining the relationships between stresses, displacements and performance.
