Abstract

Pakistan has considerable aggregate resources owing to its extensive mountainous ranges, sets a foundation to investigate the aggregates in this study. Employing an experimental methodology, the study specifically examines and compares the physical, mechanical, and chemical properties of coarse aggregates, adhering to NHA and international specifications. Acknowledging the variability in source and consensus properties across regions, aggregate samples of varying sizes were collected from three quarries. The study aimed to investigate and compare the findings by testing samples of Thandyani, Swat, and Muzaffarabad regions by following BS and ASTM standards. Post-testing the aggregates from these quarries, the results generally aligned with some exceptions observed in Los Angeles Abrasion test, flakiness and elongation index. From results, it was realized that Muzaffarabad aggregates demonstrated better physical and mechanical properties proved to be more reliable and durable aggregates than other quarries. Due to serious environmental concerns and the depletion of natural aggregates, the study underscored the imperative to explore new quarries as alternative sources for aggregates, ensuring sustainable goals for the construction of main highways in Pakistan.
