Various geological engineering tests have been conduct for planning the boring of a new tunnel, 3.2 km long, along the national road n. 47 Valsugana. The on site tests, seismic, joints survey, SPT, RQD, PLST, have been integrated by laboratory tests on talus and rock samples collected along the tunnel trace. The data collected permitted to plan the structure at the entrances and to choose as boring technic the New Australian Tunneling Method.
