Among the various types of testing of the structures, the Petricca company carries out thrust tests on parapets of all kinds. In this case the verification was carried out in the area owned by the Superintendency of the Palatine in Rome, on a stone balustrade just consolidated, through the use of N. 1 hydraulic jack and a truck as ballast. The displacements of the structure were then measured to increase the load (determined by the tester) and finally the residual failure at the zero load was measured.
