“…The moisture variation at this level is restricted because of fully saturated condition. The observed minimal variation of moisture values for deep seated sensors is comparable to the observations made by References [24] and [13]. The sensors installed at 4 ft and 8 ft showed decline in moisture values in spite of the increase in precipitation by 3.6 inches.…”

“…Finally, the time/day of the year was evaluated for assessing the effect of seasonal variation in pavement deformation. Past literature has shown that seasonal variation is one of the major causes of volumetric variation in pavement subgrade [12,13,19]. The preceeding section about change in resistivity with season authenticates that deformation is dependent upon season/time of the year.…”

“…As moisture fluctuation is most susceptible in the pavement shoulder, it is most vulnerable to swelling and shrinkage resulting in pavement distresses [11,12]. Hence, longitudinal cracking in the pavement shoulder are the most prevalent pavement distress [10,13]. Provided the moisture change is uniform, the structure resting on expansive soil experience one-dimensional vertical movement.…”

The tendency of expansive subgrade soil to undergo swelling and shrinkage with the change in moisture has a significant impact on the performance of the pavement. The repeated cycles of wet and dry periods throughout a year lead to considerable stress concentration in the pavement subgrade soil. Such stress concentrations leads to the formation of severe pavement cracks. The objective of the research is to develop a prediction model to estimate the deformation of pavement over expansive subgrade. Two pavement sites—one farm to market road and one state highway—were monitored regularly using moisture and temperature sensors along with rain gauges. Additionally, geophysical testing was performed to obtain a continuous profile of the subgrade soil over time. Topographical surveying and horizontal inclinometer readings were taken to determine pavement deformation. The field monitoring data resulted in a maximum movement up to 80 mm in the farm to market road, and almost 38 mm in the state highway. The field data were statistically evaluated to develop a deformation prediction model. The validation of the model indicated that only a fraction of the deformation was reflected by seasonal variation, while inclusion of rainfall events in the equation significantly improved the model. Furthermore, the prediction model also incorporated the effects of change in temperature and resistivity values. The generated model could find its application in predicting pavement deformation with respect to rainfall at any time of the year.

“…Jute fiber is excellent for enhancing soil qualities since it is inexpensive, readily available, biodegradable, and environmentally friendly [15,16]. A moisture barrier and altered recycled plastic pins were utilized to stabilize the pavement distresses and the rainfall-induced slope failure in [17]. The slopes' FoS or chance of failure were displayed in ASCII format in [18].…”

Heavy rainfall is often responsible for embankment failures. During intense rainfall, the embankment slope inclination is vital for slope stability. Some failures occur in the slope due to heavy rainfall and sudden change in the matric suction. Jute fiber is a reinforcing material that is added to improve soil strength. In this research, in order to explore the effects of slope inclination on soil stability, soil samples were collected and exposed to artificial rainfalls. This study presented various tests performed on the soil samples. Different tests like sieve analysis, permeability test, Direct Shear Test (DST), liquid limit, plasticity limit, and numerical modeling were conducted in the laboratory. The study's findings revealed that the failure is caused by a soil suction loss when the inclination of the slope is higher than the soil friction angle and the collapse is caused by the positive water pressure at the slope's toe when it is lower than the soil's friction angle. Furthermore, when the slope angle increases, the slopes are becoming increasingly vulnerable to rapid collapse. After that, jute fibers were combined with the soil to improve its performance. Samples of 2, 3, and 4 rows of jute fibers were tested. These jute fiber samples performed better than the ones without fibers under different rainfall conditions. The distribution of jute fibers had a favorable influence on both strength measurements and safety aspects. Utilizing the factor of safety and matric suction, the performance of jute fiber samples is superior to those without jute fibers. Consequently, by adding jute fibers the stabilization of the soil is significantly improved along with its factor of safety.
