- •
An equivalent relationship between film thickness and loading rate existed in binder bond strength (BBS) test.
- •
Different additives had significant impacts on the adhesion and self-healing properties of asphalt.
- •
Oil compromised the bond strength of SBS-modified asphalt, while both PPA and sulfur improved that.
- •
The complex modulus of asphalt had a dual effect on the results of the BBS test.
- •
The BBS test could be applied to reflect the mixture resistance to water damage.
