水泥稳定碎石的强度检测方法主要包括以下两种：

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

　　一、标准压实试验法

　　1、 Standard compaction test method

　　取样：

　　Sampling:

　　应在拌和场料车内或摊铺机受料斗内取样，确保样品具有代表性。

　　Samples should be taken from the mixer truck or the receiving hopper of the paver to ensure representativeness.

　　取样时应注意在尚未碾压的摊铺层上取到结构层的底部，并且多取几个断面，每个断面在左、中、右各取3个点。

　　When sampling, attention should be paid to taking samples from the bottom of the structural layer on the unrolled paving layer, and taking multiple sections, with 3 points taken from each section on the left, middle, and right.

　　制件：

　　Components:

　　按照规定的压实度标准制备试件，通常使用标准压实仪进行压实。

　　Prepare specimens according to the prescribed compaction standards, usually using a standard compactor for compaction.

　　试件制备过程中应控制密实度、含水量等参数，确保试件质量。

　　During the preparation process of the specimen, parameters such as compactness and moisture content should be controlled to ensure the quality of the specimen.

　　养生：

　　health preservation:

　　试件制备完成后，应进行标准养生，养生条件包括温度、湿度等应符合规范要求。

　　After the preparation of the test piece, standard curing should be carried out, and the curing conditions including temperature, humidity, etc. should meet the requirements of the specifications.

　　养生期的最后一天，应将试件浸泡在水中，以便进行后续的抗压强度测试。

　　On the last day of the health preservation period, the specimen should be soaked in water for subsequent compressive strength testing.

　　抗压强度测试：

　　Compressive strength test:

　　使用压力机对养生后的试件进行抗压强度测试，记录试件的破坏荷载。

　　Use a press to test the compressive strength of the cured specimens and record the failure load of the specimens.

　　根据试件的尺寸和破坏荷载，计算抗压强度值。

　　Calculate the compressive strength value based on the size of the specimen and the failure load.

　　二、动强度试验法

　　2、 Dynamic strength test method

　　设备准备：

　　Equipment preparation:

　　使用专用试验机，该试验机应具备锤击和冲击功能。

　　Use a dedicated testing machine that should have hammering and impact functions.

　　试件准备：

　　Preparation of test specimens:

　　试件的制备与标准压实试验法相同，确保试件质量符合规范要求。

　　The preparation of the specimen is the same as the standard compaction test method to ensure that the quality of the specimen meets the specification requirements.

　　动强度测试：

　　Dynamic strength test:

　　将试件放置在试验机上，进行锤击和冲击试验。

　　Place the specimen on the testing machine and conduct hammer and impact tests.

　　记录试件的破坏情况，包括破坏荷载和破坏形态。

　　Record the failure condition of the specimen, including the failure load and failure mode.

　　根据试验结果，评估水泥稳定碎石的动强度性能。

　　Evaluate the dynamic strength performance of cement stabilized crushed stone based on experimental results.

　　注意事项

　　matters needing attention

　　检测方法的选择：

　　Selection of detection methods:

　　应根据具体工程要求和实际情况选择合适的检测方法。标准压实试验法适用于固结较好的水泥稳定碎石，而动强度试验法适用于各种情况下的水泥稳定碎石。

　　Suitable testing methods should be selected based on specific engineering requirements and actual situations. The standard compaction test method is applicable to cement stabilized crushed stone with good consolidation, while the dynamic strength test method is applicable to cement stabilized crushed stone under various conditions.

　　试件制备的质量控制：

　　Quality control of specimen preparation:

　　试件制备过程中应严格控制密实度、含水量等参数，确保试件质量符合规范要求。试件的尺寸、形状等也应符合测试标准。

　　During the preparation process of the specimen, parameters such as compactness and moisture content should be strictly controlled to ensure that the quality of the specimen meets the specifications. The size, shape, etc. of the test piece should also comply with the testing standards.

　　测试设备的校准和维护：

　　Calibration and maintenance of testing equipment:

　　测试设备应定期进行校准和维护，确保测试结果的准确性和可靠性。

　　Testing equipment should be regularly calibrated and maintained to ensure the accuracy and reliability of test results.

　　安全操作：

　　Safe operation:

　　在进行抗压强度测试时，应遵守安全操作规程，防止发生意外事故。

　　When conducting compressive strength testing, safety operating procedures should be followed to prevent accidents from occurring.

　　综上所述，水泥稳定碎石的强度检测方法主要包括标准压实试验法和动强度试验法。在检测过程中，应严格控制试件制备质量、选择合适的测试设备和方法，并遵守安全操作规程，以确保测试结果的准确性和可靠性。

　　In summary, the strength testing methods for cement stabilized crushed stone mainly include standard compaction test method and dynamic strength test method. During the testing process, the quality of specimen preparation should be strictly controlled, appropriate testing equipment and methods should be selected, and safety operating procedures should be followed to ensure the accuracy and reliability of test results.
