GIS Imagery - ASIS Map

Recommendations & Conclusion

Aggregate is an integral part of infrastructure development all over the globe.

Few fundamental engineering properties are being studied at

Construction Materials Research Group (CMRG) at NED University

To develop a materials characterization relational database

Location of quarries and crushers: characteristics and nearest availability

Development of aggregate source information system - ASIS

To acquire Information about the Quarries and Crushers.

To compile the data of engineering properties of Aggregates.

To prepare a Web-GIS based map depicting the information of aggregate availability and their significant properties.

To facilitate the construction industry in terms of, quality, demand, location and transportation of materials.

To share the knowledge in academics and industry regarding the selection of aggregate on the basis of

engineering performance and location

•Identification of Quarries and Crushers

•Collection of inherent and crushed rock samples

•Locating the position of quarry and crushers

Sample Collection

•Execution of Tests for Coarse and Fine Aggregates

•Evaluation of engineering properties

•Petrographic Studies

Aggregate Testing

•Plotting the Location of Quarries and Crusher

•Uploading the aggregate properties

Development of

GIS Imagery

User friendly web based aggregate database

www.cmrg.neduet.edu.pk

Spatial information of aggregate

The web based ASIS has the capability to be modified

ASIS should be periodic and extensive

Narrow down the distances of selection of quarries and crushers

More standard tests are to be included to make it reliant

Should be publically free and available

ASIS map of other part of country

Serve as land marks for other products and services
