Aggregate Suitability Assessment of Wargal Limestone for Pavement Construction in Pakistan

This paper presents the evaluation of potential aggregate source for pavement construction in Pakistan. Recently demand materials has been increased significantly due to establishment China-Pakistan Economic Corridor (CPEC) Projects. Therefore, it is essential look new resources along with CPEC routes consideration this increasing demand. In context, a Physical and Mechanical characterization investigation carried out on Permian Wargal Limestone from Zaluch Nala, Salt Range explore their utilize as materials. The studied samples have tolerable values all standard engineering parameters, proposed by various national international agencies such AASHTO, ASTM, BS, NHA. Furthermore, performance indicator overall quality, evaluated mechanical qualities were integrated into single characteristic, Toughness Index (TI). TI also suggested that limestone aggregates meet quality standards construction. On basis geotechnical testing (TI), late limestone, Range, strongly recommended resource mega projects other projects.
