Suitability Assessment Of Margalla Hill Limestone As An Aggregate In Road Construction

Abstract

The studies consist of engineering properties of Margalla Hill Limestone, located in Golra Chowk 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 the laboratory of the Construction Technology and Training Institute (CTTI). Engineering properties of Margalla Hill Limestone were characterized on the basis of laboratory test results derived from the 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 the 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). A comparison between geotechnical test results and standards showed that Margalla Hill Limestone aggregates are suitable for road construction activities.
