Semi-flexible Pavement Mixture Performance And Its Design Method

The semi-flexible pavement is a kind of rigid and flexible pavement, which is formed by filling the special cement slurry into the big-interspaced asphalt mixture.On the base of researches inside and outside of the country, and recurring to many kinds of test methods, the mix design of cement slurry and mother asphalt mixture has been studied, and the corresponding design method has been brought forward. At the same time, the paper has put up a series of researches about the semi-flexible pavement performance and analyzed the mechanism of strength formation by means of electron microscope. Finally, the paper has studied the cement-emulsified asphalt mixture. The paper analyzed the mechanism of strength formation, brought forward the mix design method and evaluated its performance.We hope the achievement of this study can promote the popularization and application of the semi- flexible pavement in our country.
