What is it about?
ER is obtained by calculating the ratio of work of adhesion and the work of stripping. This method can be used as the reference for the evaluation of asphalt adhesion.

Why is it important?
Weak adhesion between asphalt and aggregates is the main cause of moisture-induced damage for asphalt pavement, especially for foamed warm-mixed asphalt pavement, because of low mix temperatures and residual moisture left behind by the microscopic foaming process.
Perspectives
The results may show that the resistance to moisture-induced damage of asphalt is improved after foaming process.
