Toa Road Corporation

Established in Tokyo in 1930, Toa Road Corporation is a Japanese civil engineering firm. The company specializes in the construction and enhancement of vital infrastructure, including road networks, expressways, and national routes, alongside related structures like bridges and tunnels. Beyond roads, their expertise extends to significant civil works such as airport development, high-speed rail, railway container yards, and photovoltaic power generation projects. They are also actively involved in regional development initiatives and disaster recovery efforts. A core component of their operations is the manufacturing and sale of a diverse array of paving materials. This includes various asphalt types, such as emulsions for roads, railways, landscape, and sports facilities; standard asphalt mixtures; and specialized polymer-modified asphalt designed for demanding conditions like heavy traffic, porous pavements, bridge decks, or cold climates. They also produce pavement materials for general applications like garages and bridges, as well as specialized landscaping solutions for historical sites and parks, and sports surfaces for running tracks, baseball stadiums, tennis courts, and bicycle racetracks. Furthermore, Toa Road Corporation provides environmental services, encompassing the surveying and remediation of soil pollution, and designs and builds underground reservoirs. They undertake demolition for urban redevelopment projects, clearing buildings, factories, and chimneys. The company also offers comprehensive road maintenance planning, integrating advanced pavement management techniques from inspection and diagnosis to performance evaluation, forecasting, and rehabilitation design, all supported by asset management principles.
