CULVERTS (SMALL-SIZE BRIDGES) AND LARGE DIAMETER PIPES
Argentine patents Nº 234827 and 252629
Undulated, parabolic-shaped plates with 2.00, 3.00, 4.00 and 5.00 meter span.
Their height is one-half the span.
They are 1.20 m wide each, and are assembled next to one another until the other side of the road is reached.
They are embedded.
Recommended minimum depth of soil cover is 0.50 m.
1. In 1984, a live load test was carried out by Neuquén’s Provincial Office of Roads and Highways in provincial route Nº 56.
2. Also in 1984, a test was performed by INTI (acronym in Spanish for National Institute for Industrial Technology), which authorized their use nationwide.
3. In 1986, another test was carried out at Instituto del Cemento Portland Argentino (Argentine Portland Cement Institute). The results of the testing showed that a 3.00 m span plate collapsed under a load of 110 tons/m2, where the standard soil cover depth had not been complied with.

SOLID TECHNOLOGICAL BACKGROUND:
Carlos A. Gschwind is an expert from Argentina with over thirty-six-year-long experience in the study, development and manufacturing of ferrocement products. Ferrocement is currently being widely used to build thousands of boats and pontoons worldwide.
In June 2015, Mr. Gschwind was invited to give a lecture at the 11th International Symposium on Ferrocement, held at the University of Aachen in Germany. Before experts from all over the world, he spoke about his over three-decade work building pontoons, swimming pools, culverts and coastal defenses, among other products, out of ferrocement.
