Rutting and Fatigue Analysis of Flexible Pavement using KENPAVE and IITPAVE: A Review

Pavements are the vital part of any highway system. Due to harsh climatic conditions and premature distresses, pavements are falling apart in initial years of construction, even though they are designed for 15-20 years. Furthermore, pavements frequently fail prematurely due to poor quality control during construction, high axle loads, extreme weather conditions, and insufficient maintenance funding. Understanding the deterioration pattern of the flexible pavement is necessary to take the decision for strengthening the pavement. Premature failures like rutting and fatigue in flexible pavement causes severe distresses in the pavement. The designers adopt the new Mechanistic-Empirical (M-E) pavement design procedure rather than the old empirical design approach for designing pavement structures effectively and efficiently. KENPAVE and IITPAVE software give the pavement responses in terms of stresses and strains and have significant influence on performance prediction which is based on the M-E design approach. This paper reviews the existing literatures on the response analysis of flexible pavement using KENPAVE and IITPAVE. The selection of materials for the pavement and the performance of pavement can be evaluated more accurately with KENPAVE and IITPAVE
