DESCRIPTION

Section between Arruda dos Vinhos and Carregado, which develops essentially in overconsolidated and evolutive Jurassic marls. 7 viaducts with a total length of 4.275m, 3 over and underpasses, 5 embankments treated with quicklime and 2 reinforced concrete pile walls, anchored in two levels, with 265m extension each, were designed. In the A10/A1 interchange, in Carregado, the alluvional deposits of the Tagus River were crossed, with 30m thick compressible clay levels, overlaying Miocenic formations. This interlink includes 3.000m of viaducts and 1.000m of embankments with about 4m maximum height that, in the contiguous areas to the autoroute A1, had load transfer platforms over
foundation piles.
