Four representatives from Iran's national highway transportation industry arrived in Sanmenxia on July 15 to carry out exchanges and study highway construction techniques.
The delegation paid a visit to Ruida Road Maintenance Engineering Company, Sanmenxia's leading road maintenance company, which is affiliated with the city's highway authority.
Micro-surfacing, a type of low cost and skid-resistant maintenance technology, is widely used on many highways, such as National Highways 310 and 209. At the construction site of the former, the Iran representatives carried out an in-depth discussion on its operational processes.
The Iran representatives spoke highly of the mature application of micro-surfacing construction technology and planned to make use of highway maintenance techniques, which is sure to help the development of the Iranian highway industry.
