The development of any country relies upon the transportation modes, networks and the manners by which they are being kept up with. Similar turns out to be true for second highest populated and developing country like India. For interfacing the regions and keeping up with smooth progression of traffic, the construction of new and developed roads are a must. A similar will be accomplished with the execution of the Bharatmala project. Under the plan, a large group of new roads will be set down in the country. Total road construction as per the draft of the scheme, government and the ministry will strive to complete new roads, which will add up to a 34, 800 kms. National highways account for 2% of the total road network and carry over 40% of complete traffic. Highway development in India expanded at 17.00% CAGR between FY16-FY21. In spite of pandemic and lockdown, India has developed 13,298 km of highways in FY21. In FY21, 13,298 kms of highway was developed across India. India Union Minister Nitin Gadkari announced that India holds the world record for fastest road construction. India has entered Guinness World Records by building a 2.5 km 4-lane concrete road within 24 hours. National Highways Authority of India (NHAI) plans to construct national highways in 2022-23 at a pace of 50 km per day.The need for sustainable bitumen highway design and construction is becoming a priority within the transportation industry. This trend is necessitated by the high diminishing rate of construction materials, pressing demand on existing landfill sites, rising dumping fees, and reduced emissions into the environment. Recycled Concrete Aggregates (RCA) as sustainable aggregates in Hot Mix Asphalt (HMA) is therefore investigated in this research article. This study examined the incorporation of various fractions of RCA at 25%, 50%, 75% and 100% replacement to fresh aggregate.
