| Abstract: | The characteristics of semi-flexible base and mixture are introduced. The features of microstructure of cement emulsified asphalt mixture are observed through scanning electron microscope. The results indicate that cement emulsified asphalt mixture consists of gravels wrapped by asphalt, cement grains and thready hydrated production of cement; the mechanical properties of mixture can satisfy the requirements of specification. |
