Flexible pavement modelling using Kenlayer
MetadataShow full item record
Road is one of the main infrastructures that play a crucial role in economy development of countries. Pavement engineering is a key factor to design and construct optimum roads. Flexible pavement is one of the most applicable method in road construction that is made in a series of layers. The construction of this type of pavement is very fast and easy to repair and have a greater resistance in a wide range of temperature and additional layer always could be added at any time. There is a various modelling software to analyse flexible pavement structure. Kenlayer is one of the most effective application in analysing flexible pavement engineering. In this paper, the well-known FEM package of kenlayer was used to evaluate flexible pavement deflection and stress distribution. In this research, the effect of different parameters such as layer moduli and poisson's ratio were changed and the stress and deflection were compared.
