What is the required temperature when the mixture with sulfur modifier leaves the plant?

The appropriate temperature for a mixture with a sulfur modifier when it leaves the plant is crucial for ensuring proper handling and performance of the asphalt in its application. This specific temperature range, between 130 and 140°C, is optimal because it allows the sulfur modifier to adequately react and blend with the asphalt binder. At this temperature, the viscosity is also manageable enough for transport and application without compromising the structural integrity of the mixture.

If the temperature is too low, the sulfur may not fully incorporate into the asphalt, leading to reduced performance characteristics like adhesion and durability. Conversely, if the temperature exceeds this range, it can lead to overheating, causing potential degradation of the asphalt binder or the modifier itself, which could negatively affect the properties of the final product. Therefore, maintaining the mixture within this specified temperature range is fundamental to achieving the desired performance criteria in asphalt applications, ensuring longevity and reliability.
