Building Smarter Roads: Sustainable Infrastructure with Ready-Made Asphalt Blocks

Abstract

The construction industry is one of the significant contributors to Greenhouse gas emissions; hence, it has become under pressure to adopt sustainable practices and reduce the environment. At this point, readymade asphalt blocks are an alternative to traditional asphalt mixtures to enhance the efficiency and sustainability of the road construction project.  Considering this fact, this study investigated the potential of readymade asphalt blocks for supporting sustainable infrastructure by which environmental and regulatory forms can be achieved to align with the vision of 2030 and COP28 sustainability goals. This work involved semi-structured interviews with industry experts to investigate trends in sustainable construction. The findings suggest that these blocks can expedite construction timelines and reduce carbon footprints. However, challenges like high cost, logistical requirements, and skilled labour demand can hinder the white spray direction of these sustainable materials for road construction; for that, a road map has been provided to influence readymade blocks that align with sustainable development goals.
