bitumen A dense, highly viscous hydrocarbon derived from petroleum, classified into two main types:

1. Natural bitumen found under hills and oil lakes
2. Refined bitumen is the result of sedimentation of crude oil

This material ^is black to dark brown in color and dissolves completely in carbon sulfide and carbon tetrachloride. Bitumen is solid at ambient temperature. But as the temperature increases, it turns into a paste and then becomes liquid. The main uses of bitumen are due to the presence of two important properties of this substance:

• impermeability against water;
• stickiness
