AB  - Structure deterioration is a process in which damage to structure begins to develop due to a combined
impact of loads and environmental conditions around the location of the structure. In general, researchers seek
to analyze the extent to which changes in the mechanical behavior of soil under a structure when hampered by
a dry and wet cycle. This research was conducted in order to analyze changes in CBR and the unconfined
compressive strength of soft soil due to the dry-wet scenario. Laboratory investigation results showed that due
to the dry-wet cycle, the CBR and UCS values had decreased, particularly during the initial cycle, when the
CBR and UCS values dropped dramatically by 77 and 87%. Moreover, by increasing cycles, the CBR and UCS
value decreases. This relatively large decrease is influenced by changes in the formation of soil microstructure
particles, the binding particles of which become tenuous due to the presence of water. At the saturated
condition, CBR and UCS value might decrease by 90%. This result can be considered in the implementation
of road construction in tropical climate zones where the wet-dry and the dry-wet cycle is a very important factor
in the behavior of the road layers. One of the measures to be taken to solve this problem is to use chemical
stabilization to increase the mechanical index of water content modification or using impermeable protection.
