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

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

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
