At what temperature does asphalt burn off?

Asphalt typically begins to burn off at temperatures around 538°C (1000°F). This temperature represents the point at which the organic compounds in asphalt can combust when exposed to sufficient heat and oxygen, leading to a loss of material and potentially creating harmful emissions. This property is crucial for understanding the handling and safety measures required when working with asphalt in construction and paving operations. Knowing this threshold helps professionals to avoid overheating during processes such as mixing and placement, ensuring quality control and safety when working with asphalt materials. The other temperature options are either below or above the burning point of asphalt, making them less relevant in this context.
