The invention refers to a new eco-innovative and sustainable “BcR_G” Road Concrete based on high quality Portland cement with recycled waste from: 1) uncontaminated concrete in the form of alternative aggregate successfully replacing non-renewable natural aggregates, derived from the recycling of concrete waste, collected, sorted, washed, ground/sorted into 4/8 mm particle size fractions and 2) glass in the form of under-100 µm powder, as a secondary raw material (1.39÷2.8)% of the cement quantity, solving an environmental pollution problem by reducing landfill waste and the exploitation of natural aggregate, with various applications in the field of construction, i.e. infrastructure, roads, platforms, pavements, etc. , becoming a composite material with high abbrasion resistance and high mechanical strength, for improving the quality of life through sustainable design.
