Evaluation of Dina Aggregates for Pavement Construction in Pakistan

Abstract:

This paper presents the evaluation of the potential aggregate source for pavement construction in Pakistan. The Dina quarries which produce quartzite aggregates have been in use for building construction for long time. For pavement construction the aggregate materials are mostly obtain from Margalla hills and Kirana hills. The crushed limestone from Margalla source has been in use for both building and road construction from decades. The Kirana hills aggregates have been also used in many road construction projects in Punjab. The purpose of this research is to see the performance of Dina quarries as potential aggregates for pavement construction. For this purpose the Dina aggregate properties are compared with the Margalla aggregates which are most extensively use in pavement construction. The aggregate properties like specific gravity, water absorption, los angles abrasion, soundness, shape, crushing and impact value conform to the required pavement standards. The asphalt mixture design make with the Dina aggregate by Marshall method also shows suitable performance. These laboratory testing indicates that Dina quarries are potential aggregates for pavement construction in the Punjab province.
