Abstract

Spent catalyst is a material produced from the cracking of petroleum in oil refineries. There are two types of Spent Catalyst
produced in Oman, equilibrium catalyst from Mina Al-Fahal Refinery and zeolite catalyst from Sohar Refinery. The study
explored the possibility of using this material in highway construction in the form of aggregate replacement or filler material
in asphalt concrete mixtures. The mix design work done on asphalt mixtures containing spent catalyst from both source shows
that there is a good potential for using spent catalyst in road applications
