Designing Perpetual Pavements

Perpetual Pavements were introduced in 2000. As the idea of Perpetual Pavement gained traction over the past decade it became clear that mechanistic-empirical (M-E) design procedures needed to be modified to adapt to this new type of sustainable paving practice. This lengthy article examines tools that have been developed to design perpetual pavements for any level of traffic, and for new or rehabilitation paving projects. These include PerRoad, a computer analysis program that can be used to design Perpetual Pavements using the M-E design philosophy, a finite element program called ILLi-PAVE, and the new AASHTO Mechanistic-Empirical Pavement Design Guide among others. The author describes a number of different projects that have used or plan to use Perpetual Pavement, including projects in Oregon, California, and Afghanistan.
