Recycled aggregates (RA) from construction and demolition waste (CDW) instead of natural aggregates (NA) were analysed in the manufacture of new eco-friendly concrete. Fine (FRA) and coarse (CRA) recycled aggregates were used in different percentages as substitutes of natural sand and gravel, respectively. The results revealed Use of recycled aggregate in concrete can be useful for environmental protection. Recycled aggregates are the materials for the future. The application of recycled aggregate has been started in a large number of construction projects of many European, American, Russian and Asian countries.

Applications of reclaimed asphalt pavement in India A review
RAP exemplifies crushed, milled and removed material from the pavement for reconstruction and excavation (see Table 3).There are several in-situ and ex-situ methods available for RAP production depending on the site conditions and applications (Taha et al., 2002), (Saride, 2010).It contains aged bitumen, which is assumed to create Engineering products’ sustainability has changed from being a choice to a crucial requirement. In this study, the impact of employing 20 % fly ash (FA) and/or 12 % silica fume (SF) as cement substitutes in the production of recycled aggregate concrete is examined. The examination was conducted in two stages, evaluation stage and analysis Sustainability framework of recycled aggregate concrete

Recycled Aggregate Concrete for Transportation Infrastructure
Recycled aggregates used in this study were generated by crushing of concrete cubes tested in the laboratory. Five different concrete mixes were produced; three recycled aggregate concrete viz with 50%, 75% and 100% recycled aggregates with fly ash, and two natural aggregate concrete mixes with and without fly ash, respectively.The construction industry is a major consumer of natural resources, with global virgin aggregate production expected to rise to approximately 60 billion tons in 2030 [1,2,3].Simultaneously, construction and demolition (C–D) waste accounts for a large portion of solid waste, and its consumption is increasing rapidly worldwide [4,5,6].Buildings Free Full-Text Performance Improvement of Recycled
