Improvement of IBA after metals removal
Sato and Fujikawa, Fukuoka U
Aging method
Why does the CBR value decrease with increasing the aging days ?
IBA undergoes self-solidification and its unconfined compressive strength increases as the curing progresses.

The “aging day” parameter refers to the time spent in the landfill.

Relationship of compressive strength and number of curing days (T-city)
The parameters “Curing days” refers to the number of days since excavation from the landfill occurred to the unconfined compression test date.
