POTENTIAL FOR CONCRETE CONTAINING MARGINAL AGGREGATES FOR USE IN CONCRETE PAVEMENT
Abstract eng: This study presents a laboratory testing results of eight marginal aggregates and two standard aggregates. The physical properties of the aggregates were first determined and different concrete mixes prepared from them. The concrete mechanical and thermal properties were inputted in finite element software (FEACONS) to determine the critical stress in a typical concrete pavement in Florida. The critical stress- strength ratio was used to evaluate the different mixes. It was found that, in general, concrete containing marginal aggregates have higher stress to strength ratios compared with concrete containing standard aggregates.
