"Evaluation of Green Roller Compacted Concrete Behavior in Rigid Pavement for Roads"

Abstract

The main objective is to study the effect of using local byproduct pozzolanic and local available nano materials, and two types of fibers on the roller compacted concrete (RCC) with investigate the different properties and structure behavior of the (RCC) pavement slab, with and without fibers under three load cases (center, edge and corner) were rested on four types of subgrade (K0, K1, K2 and K3). Results shows an improvement for all tested parameters with using byproduct materials, more improvement when using nano-materials and best results were use both, with added 1% polypropylene fibers.
