"Raw experimental data for: Dose‑dependent mechanical behaviour of tropical subgrade soils under LABSA contamination"

This dataset contains soil characterisation data, compaction and CBR test results (n=3), ANOVA and power analysis outputs, and regression model predicted values for two tropical residual soils (clay and sand) treated with 0–20% LABSA by dry mass. All CBR values are recalculated from peak loads using standard loads (13.24 kN for 2.5 mm, 20.02 kN for 5.0 mm).本数据集包含土壤特性表征数据、击实与加州承载比（CBR, California Bearing Ratio）试验结果（样本量n=3）、方差分析（ANOVA, Analysis of Variance）与功效分析输出结果，以及针对两种经按干质量计掺加0~20%直链烷基苯磺酸（LABSA, Linear Alkyl Benzene Sulfonic Acid）处理的热带残余土壤（黏土与砂土）的回归模型预测值。所有加州承载比（CBR）数值均基于峰值荷载，采用标准荷载（2.5mm对应13.24kN、5.0mm对应20.02kN）重新计算得到。
