Near-surface soil moisture content variation is a major factor in the frequent shallow slope failures observed on Mississippi’s highway slopes built expansive clay. Soil monitored generally through borehole sensors embankments and slopes. This point monitoring method lacks spatial resolution, are susceptible to premature failure due wear tear. In contrast, Unmanned/Uncrewed Aerial Vehicles (UAVs) have higher temporal resolutions that enable more efficient of site conditions, including...

Due to cyclic wetting and drying, the hydro-mechanical behavior of unsaturated soil is impacted significantly. In order assess strength parameters, knowing important. Soil moisture content an important parameter that can define shear soil. Most highway slopes Mississippi are built on highly expansive clay. During summer, evaporation in leads shrinkage formation desiccation cracks, while during rainfall, swells due infiltration water. addition this, rainwater gets trapped these cracks creates...

Highway slopes (HWS) with or partially saturated high-plastic clay soil have typically been a source of frequent shallow slope failures. Rainwater infiltrates the soil, lowering suction, decreasing shear strength, and impacting HWS stability. Thus, it is critical to determine degree saturation when analyzing stability performance HWSs. Electrical Resistivity Imaging (ERI) offers subsurface imaging, which can be used evaluate The objective current study was identify extent failure zone an...

In Highway Embankments (HE) constructed on Expansive Yazoo Clay Soil (EYCS), in situ moisture and matric suction variations are environmentally driven variables that can significantly impact the safety of slope. The collected content data localized have low spatial resolution embankments with point borehole monitoring systems sensor instrumentation. On other hand, Electrical Resistivity Imaging (ERI) allows high is a proven method mapping subsurface geologic setting. Multiple studies...

In highway slopes (HWS) constructed on high expansive clay soil (HECS), in situ moisture variation is an environmentally driven variable that can significantly impact the safety of soil. Electrical resistivity imaging (ERI) a non-destructive method with considerable potential for subsurface mapping, which be correlated volumetric content (VSMC) and matric suction (SMS) HECS to remarkably enhance evaluation performance HWS. However, limited datasets are available evaluate accuracy feasibility...

ASCE Report Card of 2020 rated transportation infrastructure poorly for many states across the United States. Mississippi has its share challenges regarding deteriorating multimodal infrastructure. Integral parts spatially distributed are geotechnical assets such as highway embankments, retaining walls, subgrades, and bridge foundations. Traditionally, Transportation Asset Management (TAM) programs have primarily focused on pavement assessment with minimal attention to assets. Geotechnical...

Early warning (EW) can be defined broadly as the provision of timely advice prior to occurrence a highly unsafe event. Efficient data use for EW is critical component failure management in general, which encompasses activities such vulnerable zone mapping, prediction, element, prevention, planning, and action. The objective current study was propose an early protocol (EWP) highway slopes (HWS) constructed on high-plastic clay Mississippi. Six HWS were investigated, instrumented, monitored,...

Slope stability is highly sensitive to soil moisture variation, especially in the case of highway slopes central MS, typically constructed on expansive clay. Traditional borehole monitoring techniques do not offer a complete picture variation throughout slopes. In contrast high-altitude, satellite-based remote sensing data, uncrewed aerial vehicles (UAVs) with optical cameras and thermal sensors higher resolution, data-loaded pixels. Furthermore, UAV flights can be precisely timed provide...

Geotechnical asset management (GAM) is in the early stages of adoption within transportation agencies, especially Mississippi (MS). assets central are vulnerable to excessive deformation due high volume changing Yazoo clay, further impacted by amount rainfall and seasonal variations. In a climate, high-intensity events add loads on geotechnical infrastructure causing catastrophic failures. Therefore GAM program that addresses resiliency climate adaptiveness much needed. Infrastructure...
