Anotasi

PAVERS program has 9 fatigue models which are used to analyze the allowable repetitions in pavement design. Those 9 models are Westergaard, Domenichini, Eisenmann, PCA, Iwama, Tepfers Kutti, UEC, Vencon 1992, and Yao. They have their own parameters to be considered in analyzing fatigue in pavements. This study is about analyzing the influence of fatigue models on rigid pavement in Perak road Surabaya (Indonesia). Structural model of concrete pavement has been created to analyze the response of structure pavement towards the repeating load. The flexural strength at the edge of longitudinal direction along the pavements was analyzed by using PAVERS program. The result of this study shows the differences of the allowable repetitions between the 9 fatigue models in longitudinal and transversal directions of the pavements. The biggest allowed repetition value in longitudinal direction of a pavement is Iwama fatigue model (8,730,000 repetitions), and the lowest one is Eisenmann fatigue model (35,932 repetitions). These differences happen because every fatigue model has different variants of numbers for every coefficient to be served as the inputs for one fatigue formula. Results between PAVERS formulas and Research formulas have some identical values. Keywords : Fatigue models, PAVERS, Repetitions
