水泥穩(wěn)定碎石是一種常用的路面基層材料，對于其集料級配有著嚴(yán)格的要求。首先，集料應(yīng)該具有良好的顆粒形狀和表面紋理，以保證混合料的強(qiáng)度和耐久性。其次，集料的最大粒徑一般不超過37.5毫米，并且在實際應(yīng)用中根據(jù)設(shè)計要求可能會有更具體的規(guī)定。此外，水泥穩(wěn)定碎石的級配應(yīng)滿足以下幾點：

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.級配曲線應(yīng)該連續(xù)，避免出現(xiàn)粗細(xì)顆粒過度集中或斷檔的情況，以確?；旌狭暇哂辛己玫拿軐嵭院头€(wěn)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毫米的細(xì)粉含量不宜過多，通?？刂圃?%~5%之間，過高的細(xì)粉含量會影響混合料的工作性能和強(qiáng)度發(fā)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來形成骨架結(jié)構(gòu)，增強(qiáng)整體承載能力；同時也要有足夠的細(xì)集料填充空隙，提高密實度。

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.

總之，在水泥穩(wěn)定碎石的配制過程中，合理選擇并嚴(yán)格控制各種粒徑范圍內(nèi)的材料用量是非常重要的。具體的級配要求還需要參照相關(guān)技術(shù)規(guī)范和工程實際情況進(jìn)行確定。

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.
