Comparative Study on Stabilization of Expansive Soil using Cement Kiln Dust and Ceramic Dust
Abstract: In India, expansive soils cover about 20% of total land area, these soils increase in volume (swell) during winter season and decrease in volume (shrink) during summer season. Due to this contradiction behaviour many civil engineering structures constructed on expansive soils get damaged severely, out of which pavement is the most because they are lightweight and extend over large areas. Stabilization of Expansive soil is of most importance, since to …

Effect of the Position of Geotextiles on the Strength Characteristics of Subgrade Soil in Bituminous Pavements
Abstract: In the past 20 years, many new road improvement techniques have revolved around the use of geosynthetics. Geosynthetics may be used in those areas where the soil remains saturated part of the year or over clay and moist silty weak subgrade soils. The quality and life of pavement is greatly affected by the type of subgrade, subbase and base course materials. Subgrade soil is the bottom most layer of the …

Biquid Filter Based Equalization Through Plastic Optical Fiber
Abstract: Plastic Optical Fiber (POF) is increasingly recognized for its advantages in high-speed data transmission, particularly over short distances. Unlike traditional glass optical fiber, POF uses a polymethyl methacrylate (PMMA) core with a fluorinated polymer cladding, resulting in a larger core diameter that simplifies alignment and splicing. Recent advancements include the development of graded-index POF (GI-POF), where the core's refractive index gradually decreases from the center outward, minimizing modal dispersion and …
