Nano organosilane for pavement applications

A construction technique using lightweight geomaterials has many practical advantages because of their light self-weight, which makes it possible to reduce large deformations and differential settlement of soft ground or a foundation with poor bearing capacity. Nowadays expanded polystyrene (EPS) blocks are used with soil to make it lightweight material. Few applications like embankment construction, retaining walls and road construction can be mention. These blocks are manufactured by industry in regular shapes only.

This study narrates the use of post-consumer waste plastic water bottles for developing a new type encasement to confine the fly ash columns fully penetrated in soft clay. Geocell reinforced fly ash beds along with a jute geotextile separator were also placed over the fly ash columns, while the cellular mattresses were also made of same type plastic water bottles.

The study presents reinforcement parameters for a 300m high artificial sand mountain. It is first attempt to design such huge structure with geogrid reinforced soil in the world. Limit equilibrium method is used in this study. Hit and Trial method is then used to optimize the reinforcement parameters and achieve desired factor of safety. The obtained reinforcement details can be helpful in designing high rise reinforced soil structures. The reinforced soil structure is stable, economic and easy to construct as compared to unreinforced one.

Expanded polystyrene (EPS) geofoam is an interesting area in the field of geotechnical engineering and its service life is comparable to other construction materials. With different geotechnical applications of EPS geofoam involving submergence, underlying compacted soil and higher structural loads, creep deformation under compression pressure have been occurring. In this study, an attempt was made to investigate the behavior of compression creep of EPS geofoam through Plaxis 3D software.

Pipelines are lifeline structures that provide essential services to communities by transporting water, liquid wastes,oil and gas, andpetroleum products over long distances. Nowadays, nearly 75% of the oil and petroleum products aretransported yearly by pipelines. Likewise, majority of water and gas to world’s urban centers and communitiesare transported by pipelines.

Study reveals how detrimental the use of mobile phones is while driving in India

A study by researchers at the Indian Institute of Technology Bombay (IITB) has shown how using mobile phones while driving can distract drivers and affect their ability to handle hazardous situations. The results of the study has shown that both calling and texting while driving degrades the performance of a driver.

Efficient tracking and maneuvering of Chandrayaan is crucial for the success of the mission. An efficient and low cost tracking algorithm from IIT Bombay could be a solution to this.
