Fiber-Reinforced Concrete Pavement Applied in National Highway Project in Paraguay– Site Visit by the Inter-American Development Bank –

Fiber-reinforced concrete (FRC) pavement using BarChip macro synthetic fiber has been applied in the construction of National Route No. 12 in the Republic of Paraguay, with construction commencing in February 2026.

This project is a national infrastructure initiative financed by the Inter-American Development Bank (IDB). On March 10, representatives from the IDB headquarters in Washington, D.C. visited the project site. Representatives from Paraguay’s Ministry of Public Works and Communications, as well as Japan’s Ministry of Land, Infrastructure, Transport and Tourism, also participated in the site visit to observe the progress of construction.


The project follows a previous application of FRC pavement on National Route No. 5 in Paraguay and represents a continued implementation of this pavement method in national infrastructure projects in the country.


During the visit, the construction process and quality control measures for FRC pavement were presented at the site. The benefits of the FRC method were also explained to participants, including not only cost efficiency in construction but also the reduction of life-cycle costs (LCC) through improved durability.


In infrastructure development, the introduction of FRC pavement in Paraguay also contributes to improving supply chain resilience. Many countries, including Paraguay, structurally depend on imported asphalt materials. By utilizing concrete, which can be produced domestically, it is possible to reduce reliance on external supply sources. In the current global environment, reducing dependency on imported asphalt materials is an important consideration for countries such as Paraguay.

We will continue to strengthen collaboration with international organizations, including multilateral development banks, the Government of Japan, and governments of other countries, and promote the implementation of fiber-reinforced concrete technology in more countries, contributing to the development of sustainable, high-quality infrastructure while advancing our business expansion in overseas markets.
