A Bitumen Sprayer is a piece of equipment used to apply bitumen (asphalt) onto road surfaces during the construction or maintenance of roads. It is primarily used for surface dressing, tack coating, and sealing applications. The sprayer ensures that bitumen is evenly distributed across the surface to create a strong bond between the asphalt layers, promoting durability and longevity.

The machine typically consists of a tank to store the bitumen, a pump to transfer it to the spray nozzles, and a spray bar to distribute the bitumen evenly. The bitumen is heated to the required temperature for optimal spraying and flow. The sprayer is operated by a control system that adjusts the flow rate and spray width for accurate and uniform coverage.
