The Use of Roller Compacted Concrete Pavements in Argentina

The use of roller compacted concrete in high-way works started in Argentina in 1986 through a programme developed by the Instituto del Cemento Portland Argentino, ICPA (Argentine Portland Cement Institute). Several sections were designed and constructed in different areas of the country, using traditional laboratory tests, mix proportioning methods and structural design, also, the suitable equipment for each work, making possible to experiment with different climates, materials and methods. It was used, depending on the type of the work, as surface course, base and for patching. This work intends to describe experiences made up to the present and some of the most important conclusions about it.
