DETERMINATION OF THE CHARACTERISTICS OF A TWO-LAYER SYSTEM CONSTRUCTED AT THE LNEC TEST PIT

DETERMINACAO DAS CHARACTERISTICAS DE UM SISTEMA DE DUAS CAMADAS CONSTRUIDO NA INSTALACAO DE ENSAIOS DE PAVIMENTOS

A description is given of the tests used to determine the bearing capacity of a two-layer system constructed in the LNEC test pit. Plate bearing test were carried out with steel plates, 30.5 - 45.7 - 61.0 CM in diameter to determine the influence line in the surface settlements of the two-course system and to measure vertical stresses inside the soil foundation. The behaviour of the two-layer system was studied under repetitive loading by means of two other plate bearing tests during which 2 x 10000 load cycles exerting a stress equal to 2.5 KGF/CM.SQ. were applied by means of a plate 30.5CM in diameter. The original document is in Portuguese.
