Abstract: This paper deals with the effect of environment in construction work in a particular area. Surrounding environment has immense effect in construction plan, site management, costs and implementation. On the contrary, it affects the workmanship’s availability as well as material availability.… View More

Rana M M, Akhi A H, & Azad G M S I. (2018). Performance Evaluation of Bituminous Mixes with Waste Concrete Aggregate. International Journal of Advanced Structures & Geotechnical Engineering (IJASGE).

Abstract: Demolished concrete elements are the main source of Waste Concrete Aggregates (WCA). Properties of WCA differ from fresh aggregates due to the cement paste attached to the surface of natural aggregates. Waste generation is increasing day by day due to demolition of small building to construct high rise building for the accommodation of increasing population.… View More

Khan S, Nagabhushana M N, Tiwari D, & Jain P K. (2014). Comparative analysis of bituminous overlay design thickness using Falling Weight Deflectometer (FWD) and Benkelman beam deflection (BBD) method, 3rd Conference of Transportation Research Group, Kolkata, India.

Abstract: The flexible pavement is the most sought pavement in many countries like U.S, India etc mainly because of ease and low initial cost of construction and maintenance as compared to a concrete pavement. Due to the distresses caused in flexible pavements, it requires routine and periodic maintenance and strengthening in the form of added thickness.… View More

Khan S, Nagabhushana M N, Tiwari D, & Jain P K. (2015). Effect of Higher axle load on the flexible pavement performance in India using Heavy Vehicle Simulator, International Conference on Road and Airfield Pavement, Dallian, China

Abstract: With the current growth of infrastructure in India, traffic growth is very high, especially transportation of goods and services have also increased considerably in many fold and so the commercial vehicles. The current flexible pavement structure has been designed with a standard axle load of 80 kN and a tyre pressure of 560 kPA, as per Indian Road Congress-37, but numerous field studies conducted by CSIR-CRRI have shown that the trucks with standard and higher axles were found to be carrying more load than designated for them.… View More

Dey A, Dasgupta A, Kumar V, Tyagi A, & Verma A K. (2015). Evaluation of the of antibacterial efficacy of polyvinylpyrrolidone (PVP) and tri-sodium citrate (TSC) silver nanoparticles. International Nano Letters, Springer. https://doi.org/10.1007/s40089-015-0159-2

Abstract: We present silver nanoparticles as the new age broad spectrum antibiotic. Siver nanoparticles exhibit unique physical and chemical properties that make them suitable for understanding their biological potential as antimicrobials. In this study, we explored the antibacterial activity of silver nanoparticles (TSC-AgNPs) and silver nanoparticles doped with polyvinylpyrrolidone (PVPAgNPs) against Gram-negative and Gram-positive bacteria, Escherichia coli (DH5a) and Staphylococcus aureus, (ATCC 13709).… View More
