Road infrastructure is critical infrastructure supporting the foundation of supply chains in the manufacturing industry, and its construction and maintenance require advanced technology and services. It is indispensable for streamlining logistics and facilitating industrial activities, functioning as a transportation route for manufactured products and a procurement route for raw materials. Key services include asphalt and concrete paving, construction of civil engineering structures such as bridges and tunnels, repair and reinforcement of aging roads, and regular inspection and diagnosis. In recent years, technological development actively pursues digital transformation (DX) promotion and sustainability, including smart maintenance utilizing ICT and IoT, development of new materials contributing to improved durability and reduced environmental impact, and development of infrastructure compatible with autonomous driving. These technologies and services contribute to strengthening the competitiveness of the entire manufacturing industry through improvements in safety, efficiency, and durability.
