Future Design of Perpetual Pavements: Issues and Options
Perpetual pavements are considered by many pavement experts to be the long-term solution to increasing traffic volumes and related pavement rehabilitation costs and user delay costs. The paper reviews the problems that perpetual pavements are experiencing, such as moisture infiltration/damage, and layer debonding. There is no indication that the pavement design methods presented in this paper account for moisture infiltration/damage or debonding in their designs. This is primarily due to the lack of an appropriate design method, which can include infiltration/damage and debonding in its design. Analysis of current field performances of selected perpetual pavements and mechanistic-empirical predicted performances is also shown. From this analysis, three out of six perpetual pavements are performing better than expected; two pavement sections are performing as predicted, and one pavement section performing worse than expected.
