Paper by CHUPIK PRILESKY SPIES from ISCR 8th 1998 Lisbon Portugal
The first part of the paper deals with the designing of rigid pavements by means of FEM. The NE10-SOILIN program uses the NE-10 finite elements composed of subelement 2D NE-10-M (tetragonal element), subelement 3D NE-I013RJCK and subsoil element. It models the Midlins slab placed on a generally multilayer structure. Under the last layer, there can still be a model 2D with two Pastemaks subsoil constants C 1 and C2 .The article indicates 2 numerical examples. The second part indicates the selected problems connected with the diagnostics of old concrete pavements to be reconstructed (numerical accuracy of hack-calculations, including the effects of temperature and thickness of layers, elasticity moduli of cement-treated layers after 20-year period).
