What is the acceptable temperature range for asphalt according to the master range?

• A. +-10°F
• B. +-20°F
• C. +-30°F
• D. +-40°F

Answer: (C)

The acceptable temperature range for asphalt according to the master range is ±30°F. This temperature range is critical for ensuring that the asphalt mixture achieves proper compaction and adhesion during the paving process. If the temperature falls outside this range, it can negatively impact the workability and performance of the asphalt. For instance, if the mixture is too cool, it may not compact effectively, leading to increased air voids and decreased durability. Conversely, if the mixture is too hot, it can lead to issues like premature aging and thermal segregation. Maintaining this ±30°F range ensures optimal conditions for the application and longevity of the asphalt pavement. Understanding the significance of this temperature range helps pave the way for successful asphalt paving operations.
