What should be used to blow out all asphalt distribution lines at the end of the day?

The most effective method for blowing out all asphalt distribution lines at the end of the day is to use compressed air. This approach ensures that any remaining asphalt material is fully evacuated from the lines, preventing blockages and allowing for smooth operation the following day. Compressed air is a safe and efficient way to clear out lines without introducing moisture or additional flammable materials that could react with the asphalt.

Using water to clear the lines can introduce moisture, which might not only lead to bonding issues when the asphalt is reused but could also affect the quality of the asphalt application. Kerosene and gasoline, while capable of displacing asphalt, pose significant safety hazards due to their flammable nature and the environmental regulations surrounding their use. Therefore, compressed air stands out as the safest and most practical choice for maintaining asphalt distribution lines.
