Compressibility parameters of old municipal waste from two landfills in Serbia

摘要

In this paper, results related to the determination of the minimum and maximum secondary compression index (C_(αmin), C_(αmax)), i.e. the modified secondary compression index (C_(αmin), C_(αmax)), obtained from laboratory tests of municipal waste samples using the oedometer apparatus with diameter of 20 cm, are presented. The dependences of these indices and the initial void ratio arealso presented and compared with the proposed intervals of Sowers (1973). All tests were performed on artificially prepared samples with respect to the recommendations related to the dimensions of used devices and the size of the largest fractions in sample (EN 1997-1, 2007). For the sample formation, old municipal waste was used, which was taken from two landfills in Serbia: one that is no longer in use (Ada Huja in Belgrade) and another that is still in use (landfill in Novi Sad).
