Abstract:

Aggregates are the stones used in road construction and subjected to take load coming from the vehicular traffic. Selection of aggregate source plays an important role and provides a guarantee towards the pavement performance. In Pakistan, aggregates manufactured in Margalla crush quarry is considered to be the best aggregates for the pavement construction. The source and consensus properties vary throughout the quarry. One cannot rely only on testing the physical properties from the single source. This study presents the results of mechanical and physical properties of twelve aggregate sources selected from Margalla aggregate crush quarry. A ranking based methodology has been adopted to minimize the number of sources for conduction of accelerated polish stone value and surface skid resistance test. Aggregate sources were ranked based on the specific gravity and other physical and mechanical properties. A ranking based on the difference between the 'before' and 'after' polish stone value has been used for a comparison with the physical properties. Ranking based on the original Polished Stone Values was not in line with what has been determined from the basic physical properties. This study reveals that instead of conducting a number physical and mechanical tests on aggregate, one can run PSV test and obtain similar ranking for the selection of specific aggregate source.
