Numerical modelling for flexible pavement materials applying advanced finite element approach to develop Mechanistic-Empirical design procedure
MetadataShow full item record
The mechanistic-empirical design method of flexible pavement is studied. Series of numerical simulation on different combination of pavement layers is conducted. Two different loading combinations are examined and different materials properties are included. Finite element method is employed to consider especially developed constitutive model to reflect shakedown behaviour of granular materials used in base layers. In final step of simulation effects of soil-asphalt interaction is studied. Results are compared and concluded.
