水泥稳定碎石的压实控制标准主要依据公路的等级和用途来确定。以下是一些具体的压实控制标准：

　　The compaction control standards for cement stabilized crushed stone are mainly determined based on the grade and purpose of the highway. Here are some specific compaction control standards:

　　一、压实度要求

　　1、 Compaction requirements

　　对于高速公路和一级公路的基层，水泥稳定碎石材料的压实度应达到98%。

　　For the base course of expressway and first-class highway, the compactness of cement stabilized crushed stone material shall reach 98%.

　　对于高速公路和一级公路的底基层，水泥稳定碎石材料的压实度应达到97%。

　　For subbase of expressway and first-class highway, the compactness of cement stabilized crushed stone material shall reach 97%.

　　这些压实度要求确保了公路基层和底基层的稳定性和承载能力。

　　These compaction requirements ensure the stability and bearing capacity of the highway base and subbase.

　　二、施工工艺与设备

　　2、 Construction technology and equipment

　　在施工过程中，应采用集中厂拌混合料，并使用摊铺机摊铺、压路机碾压的施工工艺。

　　During the construction process, a centralized factory mixed mixture should be used, and the construction technology of paving with a paver and rolling with a roller should be employed.

　　压路机的选择应根据具体的施工条件和要求来确定，但通常应配备振动压路机和轮胎压路机进行碾压。

　　The selection of road rollers should be determined based on specific construction conditions and requirements, but vibration rollers and tire rollers should usually be equipped for rolling.

　　三、其他控制因素

　　3、 Other control factors

　　含水量：应在混合料略大于最佳含水量的1个百分点时进行碾压，以确保达到规定的压实度。

　　Moisture content: Rolling should be carried out when the mixture is slightly above 1 percentage point of the optimal moisture content to ensure that the specified compaction degree is achieved.

　　延迟时间：从加水拌和到碾压终了的延迟时间不应超过水泥的初凝时间，以避免混合料硬化和压实效果不佳。

　　Delay time: The delay time from mixing with water to the end of compaction should not exceed the initial setting time of cement to avoid poor hardening and compaction effect of the mixture.

　　配合比：应严格按照设计要求的配合比进行拌和，确保混合料的均匀性和稳定性。

　　Mix proportion: The mixing should be strictly carried out according to the design requirements to ensure the uniformity and stability of the mixture.

　　四、检测与评定

　　4、 Testing and evaluation

　　在施工过程中，应定期对压实度进行检测，可以采用核子密度仪或灌砂法等方法进行检测。

　　During the construction process, the compaction degree should be checked regularly, and methods such as nuclear density meter or sand filling method can be used for testing.

　　评定标准应依据《公路工程质量检验评定标准》等相关规范进行。

　　The evaluation criteria should be based on relevant specifications such as the "Quality Inspection and Evaluation Standards for Highway Engineering".

　　综上所述，水泥稳定碎石的压实控制标准是一个综合性的要求，包括压实度、施工工艺与设备、其他控制因素以及检测与评定等多个方面。这些标准的严格执行可以确保公路基层和底基层的稳定性和承载能力，提高公路的使用寿命和安全性。

　　In summary, the compaction control standard for cement stabilized crushed stone is a comprehensive requirement, including compaction degree, construction technology and equipment, other control factors, and detection and evaluation. The strict implementation of these standards can ensure the stability and bearing capacity of highway base and subgrade, and improve the service life and safety of highways.
