Abstract

The research effort focuses on replacing and adding inexpensive materials to both pervious and conventional rigid concrete pavement. The operative use of unwanted and recycled materials in different proportions—such as rubber chips, steel slag, fly ash, and silica fume—in rigid concrete pavements is the subject of research. To test the flexural, split tensile, and compressive strengths of the concrete, cubes, cylinders, and slabs are cast. The ideal replacement content for each material was determined from earlier research investigations, and it was applied in this study to raise the standard of both conventional and pervious concrete pavements. Fly ash and silica fumes were utilised in place of 8% to 25% of the cement. The coarse aggregates were substituted with rubber chips and steel slag, ranging from 2% to 30%, respectively. In order to determine the effective percentage replacement of cementitious particles and coarse aggregates in concrete, the best replacement values were identified. Additionally, the combination of the aforementioned materials was carried out, and 1 metre by 1 metre slabs were cast. This allowed for the maximum utilisation of recycled materials in the concrete without compromising the pavement’s strength. The creation of high-quality, cost-effective concrete for the building of both conventional stiff concrete pavements and pervious concrete pavements is the main objective of this research. This will be achieved through a set of tests intended to confirm the robustness and longevity of the stiff concrete pavement.
