Abstract:
Permian and Paleocene-Eocene limestone outcrops are exposed in Western Salt Range that contains colossal quantity of mineable aggregates. Engineering properties of Wargal and Lockhart formations, Sakesar Limestone and Kalabagh Conglomerate indicated that these crushed rock aggregates could safely be used in civil work projects. Values calculated for Permian and Paleocene-Eocene limestone resources for specific gravity, water absorption, soundness, Los Angeles abrasion test, Proctor test, optimum moisture content, California bearing ratio and bitumen adhesion were much below the prescribed standards. These aggregates exhibited excellent petrographic properties and were innocuous in plain cement concrete. Moreover, they found to be hydrophobic in nature and therefore, their bond with bitumen would be durable. Development of quarries, following the environmental codes, around Dhak Pass area would provide low cost good quality crushed rock aggregate resources for Mianwali, Jhang, Bhakkar, Layyah, Muzaffargarh and Chakwal districts in Pakistan.
