Research ArticleOpen accessIn the keywordsPrediction of Permanent Deformation of Pavement's Unbounded Layers Based on Cyclic Triaxial TestsB. ŽlenderThis research presents an analytical model for determining permanent deformation of pavement's sub-grade and unbound granular base and sub-base material due to cyclic traffic loading. The model is given for interpreting results of repeated load triaxial tests. It considers long term elastoplastic behavior and resilient behavior of sub-grade and unbound granular material. Permanent deformations are expressed as a function of … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,123 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of Rutting Depth in Flexible Pavements by Using Finite Element Analysis and Local Empirical ModelAlaa H. Abed, Adel A. Al-AzzawiThe objective of this research is to predict rut depth in local flexible pavements. Predication model in pavement performance is the process that used to estimate the parameter values which related to pavement structure, environmental condition and traffic loading. The different local empirical models have been used to calculate permanent deformation which include environmental and traffic conditions. Finite element analysis … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 17 Aug 2012 · 8,741 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExperimental Evaluation of Anti-Stripping Additives Mixing in Road Surface Pavement MaterialsTienfuan Kerh, Yu-Min Wang, Yulern LinMost road surfaces in Taiwan are paved with asphalt concrete but the phenomena of rutting, cracking and stripping of the pavement are frequently occurring due to the effects of traffic flow, thermal variation and water erosion caused by rain. In this study, a series of experiments were performed to examine the effectiveness of anti-stripping fillers, which include; rock flour, rock … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,911 accessesView PDF Cite
