Hyperspectral remote sensing for characterizing asphalt binders, mastics, and mixtures under aging conditions
Vatsal Dharmeshkumar Patel, Ankush Kumar, Rishikesh Bharti, Rajan Choudhary
Case Studies in Construction Materials, 2026
Asphalt aging is a complex process that involves rheological, chemical, and mechanical changes affecting pavement durability. This research examines the aging behavior of asphalt binders, mastics, and mixtures using Viscosity Grade 30 (VG30), polymer-modified (PMB), and crumb rubber-modified (CRMB) binders. A multi-technique approach integrated rheological (MSCR, LAS), chemical (FTIR), and mechanical (IDEAL-CT) analyses with the hyperspectral remote sensing, under unaged (UA), short-term (STA), and long-term (LTA) aging conditions. RTFO/TFO and PAV were used to simulate STA and LTA for binders and mastics, and a forced-draft oven for mixtures. Results showed a 35–45 % increase in aging degree from short-term to long-term exposure across all materials, with VG30-based samples being the most vulnerable, while PMB and CRMB demonstrated enhanced oxidative stability. Hyperspectral similarity scores exhibited a strong negative correlation with both the rheological indices (R = −0.77 to −0.81) and chemical indices (R = −0.72 to −0.79), as well as a strong positive correlation (R = 0.77) with mechanical indices. These findings demonstrate the potential of hyperspectral sensing as a rapid, non-destructive tool for asphalt aging assessment. This integrated assessment furthers understanding of material behavior and advanced pavement performance monitoring. • Chemo-rheological, mechanical, and hyperspectral analyses to assess asphalt aging. • Hyperspectral indices exhibit strong correlations with asphalt aging indicators. • CRMB showed the highest resistance, while VG30 was most sensitive to aging effects. • Hyperspectral offers a rapid, non-destructive method for assessing asphalt aging.

Geological controls and exploration strategies for sandstone-type uranium ores: comparison of Indian deposits with those across the globe
Shreya Sharma, Rishikesh Bharti
Geologos, 2025
The rising global energy demand has driven researchers to locate new uranium deposits, with sandstone types contributing nearly 40 per cent of uranium production. The present review provides a comprehensive understanding of the genesis and classification and mentions some global examples of sandstone-type uranium deposits, the focus being on the geological settings of each type. Understanding these factors helps locate similar deposits, especially in North-East India, where research is limited. There, uranium enrichment is controlled by numerous factors such as source rocks, sedimentary structures, permeability barriers, reductants and cap rocks. The present study underscores the need for integrated methods for exploration of sandstone-type deposits where remote sensing can be combined with geophysical and geochemical techniques.

Tracking the Seismic Deformation of Himalayan Glaciers Using Synthetic Aperture Radar Interferometry
Sandeep Kumar Mondal, Rishikesh Bharti, Kristy F. Tiampo
Remote Sensing, 2025
The Himalayan belt, formed due to the Cenozoic convergence between the Eurasian and Indian craton, acts as a storehouse of large amounts of strain, resulting in large earthquakes from the Western to the Eastern Himalayas. Glaciers also occur over a major portion of the high-altitude Himalayan region. The impact of earthquakes can be easily studied in the plains and plateaus with the help of well-distributed seismogram networks and these regions’ accessibility is helpful for field- and lab-based studies. However, earthquakes triggered close to high-altitude Himalayan glaciers are tough to investigate for the impact over glaciers and glacial deposits. In this study, we attempt to understand the impact of earthquakes on and around Himalayan glaciers in terms of vertical displacement and coherence change using space-borne synthetic aperture radar (SAR). Eight earthquake events of various magnitudes and hypocenter depths occurring in the vicinity of Himalayan glacial bodies were studied using C-band Sentinel1-A/B SAR data. Differential interferometric SAR (DInSAR) analysis is applied to capture deformation of the glacial surface potentially related to earthquake occurrence. Glacial displacement varies from −38.9 mm to −5.4 mm for the 2020 Tibet earthquake (Mw 5.7) and the 2021 Nepal earthquake (Mw 4.1). However, small glacial and ground patches processed separately for vertical displacements reveal that the glacial mass shows much greater seismic displacement than the ground surface. This indicates the possibility of the presence of potential site-specific seismicity amplification properties within glacial bodies. A reduction in co-seismic coherence around the glaciers is observed in some cases, indicative of possible changes in the glacial moraine deposits and/or vegetation cover. The effect of two different seismic events (the 2020 and 2021 Nepal earthquakes) with different hypocenter depths but with the same magnitude at almost equal distances from the glaciers is assessed; a shallow earthquake is observed to result in a larger impact on glacial bodies in terms of vertical displacement. Earthquakes may induce glacial hazards such as glacial surging, ice avalanches, and the failure of moraine-/ice-dammed glacial lakes. This research may be able to play a possible role in identifying areas at risk and provide valuable insights for the planning and implementation of measures for disaster risk reduction.
Hydrology and sediment yield response to changes in land-use and climate in the Upper Blue Nile Basin, Ethiopia
Lewoye Tsegaye, Rishikesh Bharti
International Journal of Hydrology Science and Technology, 2025
Environmental components substantially affected by climate and environmental disruptions are watershed-scale hydrology and soil erosion. This research assessed the effects of scenario-based climate and land use land cover (LULC) changes on sediment and hydrology using dynamic conversion of land-uses and its effects (Dyna-CLUE) and soil and water assessment tool (SWAT) in Gumara watershed of Ethiopia. Climate change was analysed using GCM-RCMs outputs under SRES A1B and representative concentration pathways (RCP2.6, RCP4.5, and RCP8.5) from 2025-2099. Runoff, groundwater flow, lateral flow, and water yield decreased, whereas, evapotranspiration (ET) and sediment yield increased in both scenarios. Compared to LULC, climate change has a greater impact on reducing runoff (19-33.6%, 1.7-37.9%) and water yield (15.1-33.6%, 7.2-41.4%) in A1B and RCPs respectively. Rapid LULC conversion resulted in a significant increase in sediment yield up to 71.9% in A1B and 84.3% in RCPs.
