水泥稳定基层这种结构对原材料要求较严，严把材料质量关是保证工程质量的基

This structure of cement stabilized base for raw materials requirements more stringent, strict material quality is the foundation and an important part of the project quality assurance. Cement stabilized gravel road base materials mainly cement, gravel, water. For the good quality of raw materials, should be strengthened for all kinds of raw material sources will be determined in advance and check the required sampling frequency during use, substandard materials can not be used in the project, and should be promptly removed appearance.

Cement stability grass-roots structure of the raw material requirements are more stringent, strict material quality control is to ensure the quality of the project is the basis and important link. Cement stable gravel pavement grass-roots raw materials are mainly cement, gravel, water. In order to put good quality of raw materials, should strengthen the source of various types of raw materials in advance to determine and check, in the process of use according to the prescribed frequency sampling inspection, non-conforming materials can not be used in the project, and should be cleared in a timely manner.

The structure of cement stabilized base has strict requirements for raw materials, and strict control of material quality is the basis and important link to ensure the project quality. The raw materials of cement stabilized macadam pavement base mainly include cement, macadam and water. In order to control the quality of raw materials, it is necessary to strengthen the determination and inspection of the material sources of various raw materials in advance. During the use process, sampling inspection shall be conducted according to the specified frequency. Unqualified materials shall not be used in the project and shall be removed from the site in time.
