- •
An innovative coating treatment was modified to prepare artificial RAP substrates.
- •
A good correlation was found between asphalt film thickness and aging severity.
- •
In general, RAP brought enhancement to bond properties under dry conditions.
- •
Poor blend between RAP and virgin asphalt could lead to more water damage.
- •
A proper aging level may exist at which RAP can provide optimum bond properties.
