📋 Tender Overview
The PY05 route incorporates a multi-layer structural system specially designed to respond to the conditions of the Chaco soil and guarantee a longer useful life. This is 90 kilometers of the Concepcion-Pozo Colorado section, which will become the first national route with rigid pavement in the country. In Lot B (km 372.2 to 409.1), run by the company Ecomipa S.A., testing of the material that will make up the road surface is currently being carried out. The superintendent of works, engineer Francisco Franco, provided details about this key stage of the construction process: We are in the material testing phase, finalizing details and adjusting the equipment. Once these evaluations are completed and with the corresponding approval, we will have the green light to lay the pavement in greater length and thus speed up construction. Regarding the structure of the road package, Franco explained: The work consists of executing a gravel subgrade, considering that the Chaco soil presents particular characteristics and certain difficulties. On top of this, a granular base reinforced with cement is placed. He added that this second layer incorporates cement to increase the resistance and durability of the structure that will support the final rolling surface. Fiber-reinforced concrete is placed on top. Unlike traditional concrete, this incorporates synthetic fibers that improve its resistance and durability. The project is designed for a useful life of 20 years, but with the increased thickness applied we can estimate a life of up to 30 years, concluded the superintendent. About the work The PY05 route rehabilitation project has financing from the Development Bank of Latin America and the Caribbean (CAF) and the Financial Fund for the Development of the Countries of the La Plata Basin (Fonplata), with a total investment of G. 611,196 million and an execution period of 20 months per lot. The incorporation of rigid pavement responds to Law No. 5841/17, which promotes this technology in public works, and Decree No. 1,683/24, signed by President Santiago Pena, which regulates its application. In addition to modernizing road infrastructure, the project encourages the use of national cement and the generation of employment during its execution, strengthening the local economy and consolidating the sustainable development of the north of the country.
