水泥稳定碎石的强度检测方法主要包括以下几种：

　　The strength testing methods for cement stabilized crushed stone mainly include the following:

　　一、无侧限抗压强度试验

　　1、 Unconfined compressive strength test

　　无侧限抗压强度试验是评估水泥稳定碎石强度的一种常用方法。该试验通过专用的抗压试模，在规定的条件下对试件进行压缩，直至试件破坏，从而记录其最大破坏荷载。通过计算可以得到试件的无侧限抗压强度。这种方法能够直观地反映水泥稳定碎石在不受侧向限制条件下的抗压能力。

　　Unconfined compressive strength test is a commonly used method for evaluating the strength of cement stabilized crushed stone. This experiment uses a dedicated compression test mold to compress the specimen under specified conditions until it fails, thereby recording its maximum failure load. The unconfined compressive strength of the specimen can be obtained through calculation. This method can intuitively reflect the compressive strength of cement stabilized crushed stone without lateral constraints.

　　二、标准压实试验法

　　2、 Standard compaction test method

　　标准压实试验法是将水泥稳定碎石用标准压实仪进行压实，并在规定条件下测定压实后的抗压强度值。该方法检测结果具有较高的可重复性和可比性，适用于固结较好的水泥稳定碎石。通过这种方法，可以评估不同压实条件下水泥稳定碎石的强度变化，从而优化压实工艺。

　　The standard compaction test method involves compacting cement stabilized crushed stone using a standard compactor and measuring the compressive strength value after compaction under specified conditions. The detection results of this method have high repeatability and comparability, and are suitable for cement stabilized crushed stones with good consolidation. Through this method, the strength changes of cement stabilized crushed stone under different compaction conditions can be evaluated, thereby optimizing the compaction process.

　　三、动强度试验法

　　3、 Dynamic strength test method

　　动强度试验法是通过专用试验机对水泥稳定碎石进行锤击和冲击试验，测定其抗压强度。这种方法适用于各种情况下的水泥稳定碎石，能够模拟实际道路使用中的动态荷载情况。通过动强度试验，可以评估水泥稳定碎石在动态荷载作用下的耐久性和稳定性。

　　The dynamic strength test method is to conduct hammer and impact tests on cement stabilized crushed stone using a dedicated testing machine to determine its compressive strength. This method is applicable to cement stabilized crushed stone in various situations and can simulate the dynamic load conditions in actual road use. By conducting dynamic strength tests, the durability and stability of cement stabilized crushed stone under dynamic loads can be evaluated.

　　四、其他相关检测方法

　　4、 Other related testing methods

　　除了上述主要方法外，还有一些其他相关的检测方法可以用于评估水泥稳定碎石的强度，如：

　　In addition to the main methods mentioned above, there are other related testing methods that can be used to evaluate the strength of cement stabilized crushed stone, such as:

　　渗透性试验：测量材料对水的渗透性，确保其在长期使用中不会被水侵蚀。虽然这不是直接测量强度的方法，但渗透性的好坏也会影响材料的整体性能和稳定性。

　　Penetration test: measures the permeability of materials to water to ensure that they will not be eroded by water during long-term use. Although this is not a direct method of measuring strength, the quality of permeability can also affect the overall performance and stability of the material.

　　干缩性试验：评估材料在干燥条件下的收缩性能，以防止开裂。干缩性也是影响材料强度和耐久性的重要因素之一。

　　Dry shrinkage test: Evaluate the shrinkage performance of materials under dry conditions to prevent cracking. Dry shrinkage is also one of the important factors affecting the strength and durability of materials.

　　密度检测：采用核密度仪、动探仪等设备，检测水稳层的密度。密度是影响材料强度和稳定性的关键因素之一，因此密度检测也是评估水泥稳定碎石强度的重要手段之一。

　　Density detection: Using equipment such as nuclear density meter and dynamic detector to detect the density of the water stable layer. Density is one of the key factors affecting the strength and stability of materials, therefore density testing is also an important means of evaluating the strength of cement stabilized crushed stone.

　　注意事项

　　matters needing attention

　　在进行水泥稳定碎石强度检测时，需要注意以下几点：

　　When conducting strength testing on cement stabilized crushed stone, the following points should be noted:

　　取样要具有代表性：为了使试件的强度更接近工地现场所摊铺的水泥稳定碎石基层的强度，试件制取时取样一定要均匀且有代表性。

　　Sampling must be representative: In order to make the strength of the specimen closer to the strength of the cement stabilized crushed stone base laid on the construction site, the sampling must be uniform and representative during specimen preparation.

　　试件制备要规范：试件的成型密实度应等同于规范所规定压实度条件下的水泥稳定碎石基层现场密实度。制备过程中要注意控制含水量、装料方式、捣实程度等因素。

　　The preparation of specimens should be standardized: the compactness of the formed specimens should be equivalent to the on-site compactness of the cement stabilized crushed stone base under the compaction conditions specified in the specifications. During the preparation process, attention should be paid to controlling factors such as moisture content, loading method, and compaction degree.

　　养护条件要一致：试件制备完成后需要进行标准养护，养护条件应保持一致以确保试验结果的准确性。

　　Consistent maintenance conditions: After the preparation of the specimens, standard maintenance is required, and the maintenance conditions should be consistent to ensure the accuracy of the test results.

　　设备要校准准确：在进行试验前需要对所使用的设备进行校准和检查，确保设备的准确性和可靠性。

　　Accurate calibration of equipment: Before conducting experiments, it is necessary to calibrate and inspect the equipment used to ensure its accuracy and reliability.

　　综上所述，水泥稳定碎石的强度检测方法多种多样，应根据具体需求和实际情况选择合适的方法进行试验和评估。同时，在试验过程中要注意控制各种影响因素，确保试验结果的准确性和可靠性。

　　In summary, there are various methods for testing the strength of cement stabilized crushed stone, and appropriate methods should be selected for testing and evaluation based on specific needs and actual situations. At the same time, attention should be paid to controlling various influencing factors during the experimental process to ensure the accuracy and reliability of the test results.
