    abstract = {Pavement deterioration is a process in which damage to pavement begins to develop due to
combination impact of traffic loads and environmental conditions around location of the road. Deterioration
of road pavement function has a relatively large impact on the level of service, safety and quality of road
driving. In general, researchers seek to analyze the extent to which changes in the deformation behavior of
support layers under rigid pavement layers are hampered by a dry and wet cycle. This research focuses on the
problem of physical behavior, soil mechanics as a foundation material, focused on the impact of wet-dry cycle
treatment on soil. The mechanical parameters examined are the CBR value and the unconfined compressive
strength in wet-dry cycles scenario as well as the analysis of the performance of pavement models. Laboratory
investigation results showed that due to wet-dry cycle, the CBR and UCS values had decreased, particularly
during the initial cycle when the CBR and UCS values dropped dramatically by 82 and 85%. Moreover in
second and third cycle, the decrease in CBR and UCS values is not too significant. 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. While the pavement model test shows that the correlation
between load and soil deformation at 21 and 31% moisture content shows almost the same behavior while for
41% moisture content relatively a bit different this phenomenon shows the role of water in very large soil
masses. This result can be considered in the implementation of road construction in tropical climate zones
where the wet-dry and 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. One of material considered as used is zeolite. For this reason, this study also uses
the soft soil-zeolite stabilization as a comparison.}
