Kajima ROAD Co., Ltd. was founded in 1958 as a member of the Kajima Group, the construction group associated with Kajima Corporation. From its establishment, the company has been oriented around roads and paving, and it has grown into a specialist that combines paving with general civil engineering, asphalt mixture production and sales, and building works. Over the decades, the company has expanded its operating structure. Its corporate information page states that it now has six group companies and two overseas local subsidiaries, and that it participates in overseas projects as well as environmental protection activities. This structure supports a business that ranges from road construction and maintenance management to the supply of asphalt mixes and related construction materials. A distinctive thread in the company's history is its involvement in Antarctic regional observation. The company presents its participation as a member of the Antarctic Regional Observation Team as part of its contribution to protecting the global environment, and in September 2026 it announced that five Antarctic observation partner companies would jointly hold a report session for members of the 66th and 67th Antarctic Regional Observation Teams. In recent years, Kajima ROAD has emphasised technology development. In May 2022 it held a groundbreaking ceremony for a (tentatively named) Technology Development General Center. In November 2025 it announced the development of a new Air Foam Asphalt technology, and in January 2026 it announced a full-scale start to the development of wheel loader automation technology. In July 2026 it announced joint development with Kajima Corporation of Circular Plus Pavement, a resource-circulating high-durability asphalt pavement that uses waste plastics from construction sites. These moves reflect a strategy of combining road infrastructure work with environmental and automation technologies. The company also maintains a public-facing product line. Its sales products page lists items such as the AIJ Heater for asphalt finisher joints, Area Guard for overhead-wire proximity warning, Kajima Cool Mix and Kajima Cool Mix Aqua repair materials, Hyper Cool Patch, Falcon elastic paving material, the Midea Mix warm-mix paving method, Line Leader paving construction management, and the FOCUS system directional warning speaker. Alongside these products, the company exhibits at construction technology fairs and green infrastructure exhibitions, and it runs CSR, recruitment and community activities, including sports-related events and programmes.
