The method of vibration forming developed in recent years is most applicable to construction of expressways with the semi-rigid cement stabilized dense aggregate macadam base.

Construction technology control of cement stabilized macadam base;

Study on the causes of cracks in cement stabilized macadam base and prevention measures;

Study on application of polypropylene fibre in cement stabilized macadam base;

Cement-stabilized macadam base is a common structural type of cement-stabilized macadam base in our country,but there exist a factor that the cement dose depends directly on compression stregth,leading to addition of desiccation fissure.

In the paper , rely on the south highway of the Runyang Yangtze River Bridge,and through scanning electronic microscopic photo of cement-stabilized macadam base course, studied crack mechanism of the microstructure and the physica-mechanical characteristics as well as the influernce of cement-stabilized macadam base course,and about some fly-ash,additons etc.

Connecting with the engineering reality, this paper analyzes the quality control of the construction of cement-stabilized macadam base from aspects of the raw materials, mix proportion design, construction technology, and construction process control, etc.

207,this article describes the composition of materials for the cement-stabilized gravel base course,the mix design,the construction technology,and the quality control.

The construction techniques of cement treated macadam base are always paid more attention by highway constructors.

The temperature shrinkage stress of cement-stabilized crushed stone base is calculated with the temperature falling.

This paper introduces the types and harms of the cracks,analyzes on the reasons of the cracks generation,and probes into how to prevent the cracks generating on the cement-stabilized crushed stone base.
