What is the maximum rate of application for tack coat on paved surfaces?

• A. 0.15 liters/m2
• B. 0.20 liters/m2
• C. 0.25 liters/m2
• D. 0.30 liters/m2

Answer: (C)

The maximum rate of application for tack coat on paved surfaces is 0.25 liters/m². Tack coat plays a critical role in ensuring that the new asphalt layer adheres properly to the existing surface, promoting durability and structural integrity. The specified application rate of 0.25 liters/m² strikes a balance between achieving adequate bonding without risk of excessive material that can lead to bleeding or improper curing. It is essential to use the correct application rate to avoid issues such as tracking or a slick surface finish, which can compromise safety and performance. Using this rate ensures that there is enough tack coat to create a bonding layer while still allowing for optimal performance of the asphalt pavement.
