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 …

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 …

Fabrication and Characterization of Jute Fiber Reinforced PP-Clay-based Nanocomposites
Abstract: AbstractNanocomposite is a new concept in the field of plastic-based composites. Jute fabric (hessian cloth)-reinforced polypropylene (PP) composites with different nanoclays were prepared by compression molding. Jute fiber content in the composites was approximately 50%. Mechanical properties of PP-clay blend and PP-clay/jute fiber composites were characterized. It was found that 5% clay containing PP-clay/jute composites showed the best results. Tensile strength (TS), elongation at break (EB) and tensile modulus (TM) …

Comparative Study between Conventional and High Strength Concrete
Abstract: The current trend of use of superlatives in concrete technology may strike as somewhat disconcerting to many. We had high strength concrete, hyper-plasticizer, and super plasticizers, very reactive Pozzolana, and now high performance concrete. It is difficult to imagine any concrete being manufactured and used, which is not intended to perform to the extent; high performance concrete is not a new material of construction. The sole distinction is the level …
