The stability and durability of the infrastructures are directly dependent on quality of
aggregate shape and strength. To investigate quality of aggregate, physical characterization and Los
Angeles Abrasion Tests were performed on 15 samples collected from Murree Formation of Miocene
age. The results indicate that with respect to abrasion the Murree Formation can be divided into two
categories, in the first category sandstone and siltstone can be included where as in second category
mudstone and compact shale are placed. The Los Angeles Abrasion loss for sandstone and siltstone
range 5.76 to 22.72 %, hence can be used as crushed aggregate for roads and other construction
requirements.
