水泥稳定碎石是一种常用的路面基层材料，对于其集料级配有着严格的要求。首先，集料应该具有良好的颗粒形状和表面纹理，以保证混合料的强度和耐久性。其次，集料的最大粒径一般不超过37.5毫米，并且在实际应用中根据设计要求可能会有更具体的规定。此外，水泥稳定碎石的级配应满足以下几点：

Cement stabilized macadam is a commonly used material for road base construction, and there are strict requirements for its aggregate gradation. Firstly, the aggregate should have a good particle shape and surface texture to ensure the strength and durability of the mixture. Secondly, the maximum particle size of the aggregate should generally not exceed 37.5 millimeters, and there may be more specific regulations in practical applications according to design requirements. In addition, the gradation of cement stabilized macadam should meet the following points:

1.级配曲线应该连续，避免出现粗细颗粒过度集中或断档的情况，以确保混合料具有良好的密实性和稳定性。

The gradation curve should be continuous, avoiding excessive concentration or discontinuity of coarse and fine particles, to ensure that the mixture has good compactness and stability.

2.集料中小于0.075毫米的细粉含量不宜过多，通常控制在3%~5%之间，过高的细粉含量会影响混合料的工作性能和强度发展。

2. The content of fine powder smaller than 0.075mm in the aggregate should not be excessive, and is usually controlled between 3% and 5%. Too high a content of fine powder will affect the workability and strength development of the mixture.

3.要求有一定的粗集料比例来形成骨架结构，增强整体承载能力；同时也要有足够的细集料填充空隙，提高密实度。

3. A certain proportion of coarse aggregates is required to form a skeleton structure, enhancing the overall bearing capacity; meanwhile, sufficient fine aggregates are also needed to fill the voids and improve compactness.

总之，在水泥稳定碎石的配制过程中，合理选择并严格控制各种粒径范围内的材料用量是非常重要的。具体的级配要求还需要参照相关技术规范和工程实际情况进行确定。

In summary, during the preparation process of cement stabilized macadam, it is crucial to reasonably select and strictly control the amount of materials within various particle size ranges. Specific gradation requirements need to be determined based on relevant technical specifications and the actual situation of the project.
