Information Database Waste and Recycled Materials used in Highway/ Geotechnical- Related Applications

Date of Start: August 2002
Central Road Research Institute, New Delhi (R, I)

Present Status and Progress

The waste and recycled materials (WRM) have been used in a number of road projects in India and data is available in the form of research papers, articles, reports etc in a scattered fashion. The aim of developing the database is to make available all information to the user at one place.
To create WRM database, the required entire information is covered under the following broad categories:

General information:
A brief description and photograph of each WRM along with a conceptual presentation of its production process and potential uses.
Production and use: A pictorial representation of the graphical distribution of production and use in India and listing of reported usage.
Engineering properties: Description and listing of the physical, chemical and mechanical properties.
Environmental properties: Description of organic and leaching properties.
Application: Description of design, construction, performance and research related issues associated with the use of each WRM.
Laboratory testing: Description of recommended laboratory tests to evaluate the potential uses of each WRM.
Field testing: Description of recommended field monitoring methods to evaluate field trials.
References: References that were used to develop database.
Contacts: Government and private agencies that can be contacted to get additional information.

Information on each WRM such as fly ash, slags, mine waste, municipal waste etc. for the above nine categories are incorporated in the program files. Visual Basic 6.0 is used to develop the database which provides flexibility to update the database to respond to new data inputs.

Findings/ Conclusions
Detailed listing of engineering tests to assess the suitability of each WRM will be useful in a geotechnical related applications as well as recommendations for monitoring WRM field trials. The developed database would provide the user with both general and detailed engineering and environmental information on each WRM which will be useful to society. The waste materials have a great potential for its use in road networks.
The Visual Basic 6.0 provides the flexibility to edit and update the database to respond to new data inputs and also it is user friendly.

Limitations
More information for field trials is needed for the database. The present database is limited to information gathered from limited references/applications.

Recommendations
(i) Additional information on a specific WRM can be collected from the private and government agencies of India and that can     be included in the database.
(ii) A listing and description of recommended laboratory testing and field monitoring methods of each WRM is expected to be     included in the database.
(iii) Reports and papers on application of any other waste and recycled materials and incorporate in the data base
