BEHAVIOUR OF BALES OF COMPRESSED WOOD CHIPS UNDER VERTICAL LOAD; SOME LABORATORY TESTS

HET GEDRAG VAN BALEN GEPERST HOUTAFVAL ONDER VERTICALE BELASTING; ENIGE LABORATORIUMPROEVEN

Bales of compressed waste materials, e.g. peat dust, sawdust wood chips, have been used for roadbases for a long time. They are cheap and light in weight and especially suitable for the prevention of unequal settlement in areas where the subsoil has a poor bearing capacity. Little is known, however, about their properties and the theoretical aspects of their use. In order to study the behaviour of two types of wood chips, i.e. Shavings and fibres, under vertical load bales packed in plastic sheet were subjected to the following tests: (1) unconfined slow compression, (2) repeated loading, (3) confined stepwise compression (only fibre) and (4) CBR test. Tests nos 1 and 2 were performed with dry as well as wet material, tests nos 3 and 4 only with wet material. The following properties were determined: (a) dry density, (b) voids per cent, (C) moisture content, (D) modulus of elasticity, (e) volume change on loading, (f) California bearing ratio. /TRRL/
