Abstract:
The studies consist of engineering properties of Margalla Hill Limestone,
located in Ratta Shah area, Taxila. The study evaluates the geotechnical character
of the Margalla Hill Limestone and its suitability in road practices. By collecting
samples, geotechnical tests were performed in laboratory of Construction
Technology and Training Institute (CTTI). Engineering properties of Margalla Hill
Limestone were characterized on the basis of laboratory test results derived from
Gradation test, Los Angeles test, Specific Gravity test, Soundness test, Crushing
test and Impact value test. Laboratory test results were compared with pre-defined
standards such as American Society for Testing and Materials (ASTM), American
Association of State Highways and Transportation Officials (AASHTO), British
Standards (BS), National Highway Authority (NHA) and American Concrete
Institute (ACI). Comparison between geotechnical test results and standards
showed that Margalla Hill Limestone aggregates are suitable for road construction
activities.
