摘要

The 1986/1993 AASHTO guide is based on the serviceability concept, which is most highly correlated to pavement ride quality. This empirical approach does not necessarily assure structural integrity, nor does it directly account for the effects of pavement type (JPCP versus JRCP), joint spacing (including widened lanes), variation in material properties along a project, environmental impact, and joint design (aggregate interlock versus dowel bars) on pavement design. Further, the AASHTO guide does not effectively address the impact of the heavy, multi-axle "Michigan Truck" on the performance rigid pavements.
