soft coal also contains bitumen. Both petrol-eum asphalt and coal tar are referred to as bituminous materials. However, because their properties differ greatly, petroleum asphalt should not be confused with coal tar. Whereas petroleum asphalt is composed almost entirely of bitumen, the bitumen content in coal tar is relatively low.
