They offered me comprehensive moral support and treatment with love that enabled me succeed throughout my social and academic life.

It is an overwhelming excitement to come to this final point to express my deepest gratitude to my families TILANESH DAMTIE (MOM YOU DESERVE IT), Selamawit Setegn, Mulluken Setegn, Melak Alemu, Mekonnon Damtie (with his beloved children), Alganesh Damtie (with her beloved daughter Nebyat), who still keep up with me as the shepherd. His attitude for the development of computerized design aids for our country is something to emulate for all involved in engineering industry.

He was a friend too which I strongly appreciate and emphasize this should be a culture for everyone to get fruitful scholars.

Full-depth cores collected from the crack locations did not show any bottom-up cracking. 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. However, predicted strain values derived from the mechanistic-empirical response models were lower than tensile strains computed using moduli from the 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. Tensile strains were computed using EVERCALC software from recently collected falling weight deflectometer (FWD) deflection data. Fatigue lives of these sections were also evaluated based on bottom-up cracking. 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. 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. 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.
