Numerical Analysis of Roller Compacted Concrete Pavement
Journal Title: Saudi Journal of Engineering and Technology - Year 2016, Vol 1, Issue 1
Abstract
Abstract: There has been various design methods for roller compacted concrete (RCC) pavement during a several decades. These design procedure are developed gradually. In this paper a 3D finite element (FE) model of RCC pavement has been developed. . In the validation step, the results of 3D modelling are compared with those obtained by theoretical approach. The comparison shows good correspondences. Due to the fact the theoretical approach uses 2D model in the formula, the 3D FE model results were slightly lower than the theoretical model. Using finite element software ABAQUS software, the paper investigated effects of changes speed in vertical displacement. In order to find the effect of speed in typical RCC pavement with the assumed properties in section 3, five partition for the applying load has created on the surface of slab. Vertical displacement at the bottom of the surface layer has been achieved for six different speed. Considering the obtained results of vertical displacement of the pavement for four assumed speed, the fitted curve is drawn with high accuracy. Keywords: roller compacted concrete; finite element, vertical displacement, ABAQUS, speed.
