Design and execution of the Constanza Bypass
The Constanza Bypass forms part of the Bucharest bypass ring-road network and it is intended to improve traffic fluidity and connect the bypass to the A2 Constanza motorway.
It is 22 kilometres long and located to the west of the City of Constanza. It includes five junctions, twenty-six structures, among which there are six noteworthy viaducts, eight overpasses and six underpasses. It has two 3.75-metre lanes in each direction a 4-metre central reservation and a 3-metre emergency lane.
Most of this motorway runs along an embankment over land with very little load-bearing capacity and, because of such conditions, the seating required consistency, which was achieved using 1-metre diameter gravel columns to a depth of 6 metres for an embankment of over 5 metres high.
Its construction includes more than three million cubic metres of embankment fill-in and 2.6 of soil excavation, one million cubic metres of stabilised soil in a twenty-centimetre thick layer and the spreading of 360,000 tonnes of asphaltic agglomerate.
