Project description

The objectives of this study are to: (1) develop a revised formal mix design of the ground rubber concrete (GTR) paving concrete, with optimal selection of components based on established criteria of strength, workability, and sustainability; (2) design an experiment (considering factors such as air content, water cement ratio, etc.) for varying the amount of superfine or fine aggregate size GTR in trial mixes of rubber concrete; (3)
