Abstract
In Japan, the incinerated ash of municipal solid waste (MSW) was disposed into controlled-type landfill. In this paper, the authors conducted the unconfined tests, oedometer tests and permeability tests using acompacted samples which experienced different curing time from 0 to 180 days. (1) In case of being compacted at disposed moisture content (43%), unconfined compression strength showed increasing tendency up to a value of 1, 300kN/m2 at 180 curing days. (2) Coefficient of permeability decreased from 1×10-5cm/sec at non curing day to 1×10-8cm/sec at 180 days. (3) Compression index Cc was 0.3 for the sample with no curing days. But it lowered gradually down to a value of 0.1 as curing time passed to 180 days.
