What does the "lifting" characteristic of asphalt indicate?

The "lifting" characteristic of asphalt specifically relates to its ability to withstand load without experiencing permanent deformation. This is crucial in asphalt applications, where materials must support vehicle loads and environmental stresses without failing. When asphalt can lift or support loads without yielding or deforming, it indicates a well-designed mixture that includes appropriate binder and aggregate components.

This characteristic ensures that the surface remains smooth and functional over time, contributing to the overall durability and longevity of the pavement. The capacity for lifting under load is a key performance indicator for asphalt mixtures, and it plays an essential role in pavement design and construction practices.
