Heavy oil is a general term for non-traditional petroleum in the petrochemical industry, including heavy oil, asphalt drilling fluid treatment agents, high viscosity petroleum, natural asphalt, oil sands, and shale. Heavy oil generally does not move at room temperature and can only be extracted from the Earth's crust through heating or dilution. In a narrow sense, heavy oil primarily refers to heavy oil, which is the remaining crude oil after extracting light oils such as gasoline and diesel. Its primary characteristics are high molecular weight and viscosity, and it is mainly composed of long-chain hydrocarbons with more than 20 carbon atoms.

Asphalt is divided into natural asphalt, petroleum asphalt, and coal tar pitch. Carbohydrate asphalt is a residual byproduct of coking, which is the black volatile substance left in the distillation boiler after coal tar distillation; Petroleum asphalt is a residue of crude oil left after distillation, with a bright black viscosity; Natural asphalt exists in nature and is primarily stored underground or on the surface of the earth's crust through geological means. Natural asphalt undergoes long-term natural transpiration and oxidation, and generally does not contain any toxins; Coal tar pitch and petroleum tar pitch generally contain a small amount of harmful substances.

Asphalt is a widely used engineering material, most notably in construction projects such as road paving. The journey we generally refer to as asphalt pavement is a journey of uniformly mixing and sealing with asphalt and gravel.

In fact, people have been using asphalt for a long time. Archaeological research indicates that humans have long been using natural asphalt. At that time, people used asphalt as paint to make weapons and tools, and painted sculptures. Especially in the two river basins, natural asphalt, a drilling fluid treatment agent for asphalt, is widely used due to its sufficient content. The Sumerians who lived there used natural asphalt to cover their tableware and boats for corrosion resistance. In addition, they use natural asphalt as a binder in clay bricks to make them more durable.

In India and Europe, near two river basins, natural asphalt is widely used as a sealing material for bathrooms, canals, and dams. In the 7th century BC, in the Babylonian Empire, asphalt was used as a sealing material and paint to reinforce and decorate magnificent journeys. Since then, asphalt has also been used by ancient people as modern cement, becoming an indispensable material for building the Great Wall and sky gardens.

In 1837, extensive experiments proved that asphalt technology could be used for making journeys. In 1839, Vienna, Austria discovered a method of heating asphalt from scratch. In 1838, the first asphalt road appeared in Hamburg, Germany, and 20 years later, almost all journeys in Europe's major cities were paved with asphalt. In 1842, the production process of asphalt was invented and quickly successfully used for journey making.

At the beginning of the last century, with the continuous decline in engineering data prices, asphalt gradually became widely used. In 1907, the first batch of asphalt mixture was put into use in the United States. In 1914, the first asphalt runway was built in Berlin. In 1963, Britain adopted dry asphalt technology to quickly put airport runways into use.
