What is the minimum gallon per square yard requirement for a base, structural, or dense graded friction surface on new construction?

The minimum gallon per square yard requirement for a base, structural, or dense graded friction surface on new construction is 0.06 gallons per square yard. This specification ensures that there is adequate coverage of the surface with asphalt binder, which is crucial for achieving the desired structural integrity and performance characteristics of the pavement.

When the asphalt binder is applied correctly at this minimum rate, it promotes better adhesion between the aggregate and the binder, thus contributing to the overall durability and longevity of the pavement. Moreover, adhering to this guideline helps maintain a balance between sufficient bonding and preventing excessive binder which could lead to issues such as bleeding or raveling.

This standard plays a pivotal role in ensuring that the newly constructed roadways can withstand the anticipated traffic loads and environmental conditions. Understanding this requirement is essential for anyone involved in the asphalt paving process, as it directly impacts pavement quality and lifespan.
