The present paper demonstrate the UV-VIS analysis of various products obtained form thermal and catalytic cracking of asphalt in a micro autoclave under nitrogen atmosphere Adsorption bands correspond to conjugated benzene rings in the virgin sample indicate aromatic character. It is evident that the peaks correspond to aromatic conjugated system, unsaturation and heteroatoms are almost a feature of every spectrum which confirms that the products of cracking are unsaturated and need further hydrogenation in a seprate step before their marketable use.
