Abstract

The effect of a suspension system on the design parameters of asphalt layer in a flexible pavement using finite layers freeware 3D-Move Analysis V2.1 is evaluated. This is done trying to reproduce more closely the contact and stress of the design axle (80kN) having as new input variables the damping and dynamic movement which are not currently applied in Colombian practice. To validate, the elastic multilayer EverStress©5.0 software was used. The results of the strain can conclude that the asphalt pavement designs developed with analytical methods may be slightly oversized and consequently, the cost of construction of pavements increases. This study allows to analyze the sensitivity of various factors that may affect the design of asphalt pavements.
