Colored Asphalt: The Changing Face of Road Construction in India
The road construction industry in India is undergoing a paradigm shift: strong demand, higher investments, and the emergence of newer and more innovative technologies is giving a renewed focus on sustainable developments. These technologies include the use of improved materials for road construction like recycled materials, plastic waste, asphalt, etc.
There is an emphasis on recycled materials and reducing the amount of energy required to produce asphalt. Low-temperature asphalt is one such development. Asphalt’s core ingredients are aggregate, bitumen, additives, and air. Bitumen is produced in various grades of hardness. Depending on the mix and grade of bitumen used, it is possible to lay road surfaces to meet a variety of requirements.
