Efficient and rapid road construction enhances the development, mobility and safety of any region and sustains economic growth without any adverse impact on the environment. Traditional construction methods has significant obstacles such as schedule and expense overruns, environmental implications, labor intensity, material constraints, and traffic delays, demanding novel solutions to increase efficiency and sustainability.

Despite difficulties with transportation, collaborative design, budgets, and design constraints, precast concrete and modular construction improve road building through increased efficiency, decreased labor costs, quality control, and sustainability. It is becoming more efficient, safer, and of higher quality because to the integration of automation and robots; yet, there are still drawbacks, such as high initial costs and the requirement for expert operators.
