Question: Name the petroleum product used for surfacing of roads?

Bitumen, also known as asphalt, is the petroleum product commonly used for surfacing roads. This sticky, black, and highly viscous liquid or semi-solid is a refined form of petroleum, obtained through the fractional distillation of crude oil. It is separated from lighter hydrocarbons like gasoline and diesel during the refining process. Bitumen's excellent adhesive and waterproofing properties make it an ideal binder mixed with aggregate particles to create asphalt concrete, providing durable and smooth surfaces for roadways. Its widespread use in road construction is due to its ability to withstand heavy traffic and adverse weather conditions, ensuring long-lasting road performance.
