Title:

Perpetual Pavement Design Analysis

Accession Number:

Record Type:

Abstract:

In 2005 the Kansas Department of Transportation constructed four perpetual pavement sections on US-75 near Sabetha, Kansas, as a collectively viable alternative to full-depth asphalt pavements. These sections were designed under the assumption that horizontal tensile strain at the bottom of the asphalt concrete layer remains below the mixture fatigue endurance limit. This study re-analyzed these perpetual pavement sections using PerRoad and AASHTOWare Pavement ME Design software to investigate tensile strains at the bottom of the bituminous base. Fatigue lives of these sections were also evaluated based on bottom-up cracking. Tensile strains were computed using EVERCALC software from recently collected falling weight deflectometer (FWD) deflection data. Results showed that, compared to the AASHTOWare Pavement ME Design software, PerRoad predicted higher tensile strain values at the bottom of the bituminous base. However, predicted strain values derived from the mechanistic-empirical response models were lower than tensile strains computed using moduli from the FWD deflection data. The required asphalt thickness designed with PerRoad was also relatively higher than the asphalt thickness resulting from the AASHTOWare Pavement ME Design software throughout a 50-year design period. Full-depth cores collected from the crack locations did not show any bottom-up cracking.
