March 2012. Presently, I am being designated as Advisor (Planning and Policy Issues). After taking over as Chief

Scientist, I have taken some very critical and challenging projects and completed them successfully. In addition

4

to the above, I had actively participated in many IRC committees and drafted many Standards and guidelines

independently, which were published by IRC. I am still revising some of the old IRC Standards and Guidelines.

Some of the major projects handled by me are listed below and contributions to IRC has also been indicated.

During the last seven years as Chief Scientist, I have been involved in various research and consultancy

projects of the institute. Some of the important projects are listed below.

Quality audit of Lucknow- Muzaffarpur National Highway project (LMNHP)

The overall objective of this project is to examine the conformity of eight road projects executed/completed vis-a-

vis contract specifications/requirements by undertaking one time quality audit of these road projects. The major

objectives envisaged under this project are given below:

To identify non conformance and suggest remedial measures/corrective actions to minimise/avoid future

occurrences.

To confirm effectiveness of Quality Assurance System (QAS) adopted by the Contractors as well as by the

Project Supervision Consultants(PSC)

To suggest/recommend rectification measures towards improvements in the QAS

The project has been completed successfully.

Design and quality control aspects of Signature Bridge at Wazirabad, New Delhi

Under this project, the design and construction of approach embankments including the design of Reinforced

Earth Wall were provided by CRRI. Many innovative methods for the design and construction of high

embankments under water logged and flood prone zone areas were provided. The innovative construction

methods for high retaining walls over flyash backfill in water logged areas were suggested after exhaustive

geotechnical investigations. Many new methods for slope protection using natural and synthetic geotextiles were

incorporated in this project on CRRI's recommendations.

The project is presently under progress.

Design and construction of underpass below railway embankment using the innovative technique of Soil

Nailing.

The objective of this project was to construct an underpass below a railway track. The track was constructed on

sand embankment with a height of about 12m from the ground. The sand embankment was confined between

two stone masonry wall. The challenge of this project was to create an underpass below the railway track by

removing the wall from both the sides, which would make the soil to collapse under the dynamic loads

transmitted to soil due to the movement of train. In this project, a very innovative technique of soil nailing was

used to construct an underpass below a railway track in New Delhi during the period of Commonwealth Games

in the year 2010. Using the Soil Nailing technique for reinforcing and stabilizing a collapsible soil mass under the

dynamic loads caused by railway train movements was very innovative. The design and construction

methodology adopted for carrying out the project considering the construction risks was very unique and

demonstrates that how a simple concept can be imaginatively used to execute a project of a large complexity.

The unique use of this innovative technique will give more confidence in technologies which can be ingeniously

used for underground construction of Civil Engineering works. A patent has been filed for this innovative

technology.

Studies, Choice of Bituminous binders etc.


Use of Geotextiles in Road Construction

This was one of the major road construction projects in India on the use of geotextiles in highways construction

on soft soils. Under this project several roads in Gujarat and Maharashtra passing through black cotton soil are

and under water logged conditions were constructed using geotextiles. The objective of the project was to study

the relative efficacy of the use of geotextiles as compared to the use of conventional techniques in the

construction of road pavement on soft subgrades. Based on the field data obtained from the study a number of

important conclusions were drawn regarding the use of geotextiles in the construction of roads on soft soils. The

findings of the study helped me in the Preparation of IRC Guidelines for the Construction of Roads Using

Geotextiles (IRC: SP-58-2001)

Development of Tractor Bound Technology for Rural Roads Construction

Under this project, rural roads were constructed using tractor towed agriculture implements for various road

construction activities. The project was taken up with a view to develop a technology, which is neither purely

labour based nor machine based. In the project, an appropriate/ judicial man-machine mix was suggested for the

construction of rural roads, so that the same can be used for construction with an accelerated pace with the

added benefit of better finished quality of work and considerable time savings in the project.

Received an award from IRC for the paper published on the above project work.
