Water boiling test can evaluate the adhesion between base asphalt (A-70, etc.) and stone, but cannot evaluate the adhesion between modified asphalt, the asphalt with all kinds of anti-stripping products and stone. The reason is that modified asphalt has better adhesion than base asphalt at the same test temperature, and it is very hard to damage the adhesion interface. In this paper, a new method of water boiling adhesion test at high-temperature(120°C) was proposed, and a new test devices was invented using the mass loss rate of asphalt as evaluation parameters. Choosing three kinds of aggregate, two kinds of asphalt and a kind of anti-stripping products to proceed test research, aimed to prove the feasibility of water boiling adhesion test at high-temperature. The results showed that it is better to evaluate the adhesion between high viscosity asphalt and stone using the water boiling test method at high-temperature.
