In India road construction is emerging fast
which resulted in the increased usage of natural
aggregate. Natural aggregates are depleting due
to large quantity use in the road network
development. The depletion of natural aggregate
requires seeking out for an alternative for
aggregate in the upcoming years. Slag is an
industrial waste of iron and steel industry. The
dump of Slag is an environmental problem. In
this study, natural aggregate is replaced with
EAF and ACBF Slag in the Dense Bituminous
Macadam of flexible pavement at various
proportions of 15%, 25% and 35% and 15%,
25% respectively. The objective of this study is
to evaluate the properties of slag, aggregate and
bitumen for the preparation of several Marshall
Mixes samples using various percentage of slag
instead of natural aggregate to achieve optimum
binder content by using Marshall Method for
Dense Bituminous Macadam.
