Asphalt was first used on roads in the early 19th century. The first recorded use of an asphalt pavement occurred in 1824 in Paris, France, where it was applied to the streets. This innovative material gained popularity for its durability and waterproof qualities, leading to widespread adoption in road construction throughout the 19th and 20th centuries.

Cold Mix Asphalt is a mixture of aggregate and asphalt. Cutback asphalt is a liquid asphalt. Cold Mix Asphalt is a mixture of Aggregate and Asphalt. The Asphalt is usually am emulsion asphalt or a cutback asphalt. An emulsion asphalt is asphalt cement blended with water. Cutback asphalt is asphalt cement blended with a fuel oil, kerosene, or a naptha. The water, fuel oil, kerosene or Naphta evaporates and leaves the asphalt.
Asphalt must be liquified before it can be pumped through pipes, mixed with stone aggregates, or sprayed through nozzles. Heating is one way to liquify asphalt for construction purposes. But when asphalt cools, it becomes a semisolid material. There are other ways to liquify asphalt for construction operations. One way is to emulsify it with an emulsifying agent and water. In the emulsification process, warm asphalt is mechanically milled into very very small globules (5-10 microns and smaller) and dispersed into the water treated with emulsigying agent. The emulsifying agent keeps the asphalt globules apart from one another and suspended in the water which allows the asphalt to be used at room and cold temperatures. After the emulsified asphalt is sprayed onto a surface or mixed with aggregates the water evaporates and leaves only the asphalt residue behind to cement the aggregates together or waterproof the surface it was sprayed on.

The first asphalt road was constructed in 1824 in Paris, France, by engineer Pierre-Marie-Jérôme Tranchant. This innovative use of asphalt for paving roads marked a significant advancement in road construction. However, it wasn't until the late 19th century that asphalt became widely used for paving roads, particularly with the development of the first modern asphalt pavement in the United States in the 1870s.
Asphalt pitch is a black substance that is used to repair roads. Asphalt pitch is the liquid form of tar.
Asphalt is used most often in the construction of roads, parking lots, walkways, and other paved surfaces
