Common quality defects of cement stabilized base and prevention measures;

Due to the cracks of cement stabilized base material which reflect to pavement under the load and become reflective cracks,the precracking technology is applied for treatment on semi-rigid base,which greatly reduces the amount and severity of shrinkage cracks.

Disease and prevention of concrete stabilized base in the highway engineering construction;

This paper compares the difference of required aggregate grain size for cement stabilized soil base course in construction technical standards of China and with the United States.

Based on the construction experience of the highroad from Xinqiao to Dabeibu which is one of the projects financed by World Bank in Anhui Province,the article summarizes the construction techniques for cement stability level and the techniques for spreading the cement stability level with the use of cement-spreading machine.

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.
