	%X The present study explains the effect of aggregate
gradation on moisture damage in bituminous mixes. Three types of
aggregate gradation and two types of binder; VG-30 and Polymer
modified bitumen (PMB-40) are used. Moisture susceptibility tests
like retained stability and tensile strength ratio (TSR) and static creep
test are conducted on Marshall specimens. The creep test was also
conducted for conditioned and unconditioned specimens to observe
the effect of moisture on creep behaviour. The results indicate that
Marshall stability value is higher in PMB-40 mix than VG-30 mixes.
Moisture susceptibility of PMB-40 mixes is low when compared with
mix using VG-30. The reduction in retained stability, and indirect
tensile strength and increase in creep are evaluated for finer, coarser
and normal gradation of aggregate to observe the effect of gradation
on moisture susceptibility of mixes. The retained stability is least
affected when compared with other moisture susceptibility
parameters
