What is in asphalt cement ?

Asphalt cement, also known as bitumen, is a crucial ingredient in the construction of roads, highways, and other paved surfaces. It is a sticky, black, and highly viscous liquid or semi-solid form of petroleum, which is primarily composed of long chains of hydrocarbon molecules. The properties of asphalt cement are crucial for its performance as a binder.

Asphalt cement has a relatively high viscosity at normal temperatures, which makes it sticky and able to hold the aggregate particles together. However, when heated, it becomes less viscous and more fluid, allowing for easier mixing and placement during construction. It is also known for its ability to cure quickly and form a strong bond with the surface it is applied to.

The composition of asphalt cement can vary depending on the source of crude oil and refining processes. For example, asphalt cement obtained from crude oil will have a higher content of asphalt than one obtained from refined.

Asphalt cement is commonly used in the construction of roads, parking lots, and other paved surfaces. It is essential for the production of durable and long-lasting pavement, which can withstand heavy traffic and various weather conditions.

In summary, asphalt cement, also known as bitumen, is a crucial ingredient in the construction of roads, highways, and other paved surfaces. Its properties, such as its high viscosity and ability to form strong bonds with surfaces, make it an ideal choice for use in these projects..
