本数据聚焦于分析碎石化层密实度与顶面回弹弯沉值的关联性，揭示了二者之间的相关性强度。本数据可以给碎石施工领域的相关科研工作者、技术研发人员、工程监理人员、工程质量检验人员等使用，为他们围绕围绕碎石化层的密实度、顶面回弹弯沉值等角度开展碎石工程的相关预测分析、质量控制、科学研究、技术优化等工作提供支撑。1.数据采集：记录不同碎石化层密实度下材料的顶面回弹弯沉值测试数据，包括测试点编号、测试时间、碎石化层密实度/%、顶面回弹弯沉值/mm等字段。
2.数据预处理：（1）对采集的数据进行去噪处理，确保数据准确性。（2）把历史采集的数据（包含本次采集）进行聚合，形成数据集X，并针对数据集X中的顶面回弹弯沉值字段，计算出其平均值。
3.计算相关系数：（1）基于数据集X（以碎石化层密实度为自变量、顶面回弹弯沉值为应变量），运用CORREL函数计算碎石化层密实度与顶面回弹弯沉值之间的相关系数r。（2）相关系数r的取值范围为[-1,1]，其绝对值越接近1，表示两者之间的相关性越强；绝对值越接近0，表示两者之间的相关性越弱。
4.结果运用：若|r|≥0.8，则判定为“强相关”；若0.5≤|r|＜0.8，则判定为“中相关”；若|r|＜0.5，则判定为“弱相关”。

This dataset focuses on analyzing the correlation between the compaction degree of the crushed stone layer and the top surface rebound deflection value, and reveals the strength of the correlation between the two. This dataset can be used by relevant researchers, technical R&D personnel, project supervisors, and engineering quality inspectors in the crushed stone construction field, providing support for their predictive analysis, quality control, scientific research, technical optimization and other related work of crushed stone engineering from the perspectives of the compaction degree of the crushed stone layer and the top surface rebound deflection value.

1. Data Collection: Record the test data of the top surface rebound deflection value of materials under different compaction degrees of the crushed stone layer, including fields such as test point number, test time, compaction degree of the crushed stone layer (unit: %), and top surface rebound deflection value (unit: mm).

2. Data Preprocessing: (1) Denoise the collected data to ensure data accuracy. (2) Aggregate the historically collected data (including this batch of collected data) to form dataset X, and calculate the average value of the top surface rebound deflection value field in dataset X.

3. Correlation Coefficient Calculation: (1) Based on dataset X (with the compaction degree of the crushed stone layer as the independent variable and the top surface rebound deflection value as the dependent variable), use the CORREL function to calculate the correlation coefficient r between the compaction degree of the crushed stone layer and the top surface rebound deflection value. (2) The value range of the correlation coefficient r is [-1, 1]. The closer its absolute value is to 1, the stronger the correlation between the two variables; the closer its absolute value is to 0, the weaker the correlation between the two variables.

4. Result Application: If |r| ≥ 0.8, it is judged as "strong correlation"; if 0.5 ≤ |r| < 0.8, it is judged as "moderate correlation"; if |r| < 0.5, it is judged as "weak correlation".
