Physical- Mechanical and Mineralogical- Petrographical Characteristic of the Diabases at the Locality “Kosarska reka” (Vardar, zone, Republic Macedonia), as Basis for the use of the Diabases for Construction Stones

In this paper will be shown the results from the investigations of physical-mechanical and petro­graphic-mineralogic characteristics of on diabase Košarska Reka locality (Vardar zone, Republic of Macedonia) as a basis for application of construction stones. The analyses and the laboratory tests have been performed on samples of diabases that were taken from the surface layers. The results from their physical and mechanical analyses showed that these rocks meet the requirements for their utilization as construction stone suitable for all fractions of asphalt – con­crete, concrete aggregate, tampon material, stone dust and other application in the civil engineering related to the traf­fic infrastructure. Additionally, the quality of the stone is higher in the deeper parts of the terrain, where the external influences have little effect
