Understanding soil properties' spatial and temporal variability is essential for optimizing road construction maintenance practices. This study investigates the seasonal of properties along a 4.8 km roadway in Maiduguri, Nigeria. Using novel integration network analysis geotechnical testing, we analyzed nine parameters (e.g., particle size distribution (PSD), Atterberg limits, California bearing ratio) across wet (September 2024) dry (January 2021) seasons from 25 test stations. Average limits (LL: 22.8% vs. 17.5% dry; PL: 18.7% 14.7% PI: 4.2% 2.8% LS: 1.8% 2.3% dry), average compaction characteristics (MDD: 1.8 Mg/m3 2.1 OMC: 12.3% 10% CBR (18.9% 27.5% dry) were obtained. Network employed z-score standardization similarity metrics, with multi-threshold (θ = 0.05, 0.10, 0.15) revealing critical structural differences. During season, networks exhibited 5.0% reduction edges (321 to 305) density decline (1.07 1.02) as thresholds tightened, contrasting dry-season retaining 99.38% connectivity (324 322 edges) stable (0.99). Seasonal shifts classification (A-4(1)/ML A-2(1)/SM underscored moisture-driven plasticity changes. The findings highlight implications adaptive design, emphasizing moisture-resistant materials optimized periods.
