Applied Study on Technique of Superpave Asphalt Pavement

Through a case of Superpave asphalt pavement project, several elements of its mixture design have been introduced including material choice, aggregate structure choice, design gradation, asphalt dosage definition and mixture water sensitivity, etc.Then, the design products of some Superpave asphalt pavement projects and their tracking performance material have also been presented in this paper. It shows that Superpave asphalt pavement is of excellent high-temperature stability, better pavement levelling and service performance. Futhermore, the Superpave mixture design system is proved to be scientific and reasonable relatively.
