The aim of research to a study some Engineering properties, Mechanical abrasion (Loss Anglos) test and Californian bearing ratio (CBR), with some physical properties such as optimum water content and specific gravity tests for aggregate deposits in Kirkuk / Iraq . Six samples taken from (Chiman) and (Shurau) sits , three samples from each sit which represented (Bai Hassan Formation) from (Shurau) sit , and Quaternary deposits from (Chiman) sit to estimate its resistance to abrasion and friction of the outer surface for course aggregate to show the suitability of geotechnical qualification of road layers and concrete works. The physical geotechnical evaluation results grain size distribution for samples (1, 2, 3) are matching for class (A) with simple shift in fine sizes according designation[1], while the samples (4, 6) are matching with class (B), while sample (5) matching exactly class (A), through represented the result as a curves and matching with standard curves all samples gave well graded curves. A results of specific gravity (dry, wet) of coarse aggregate (gravel) for samples (1, 2, 3) reached at average (2.583, 2.6) respectively, while a results of samples (4, 5, 6) reached at average (2.607, 2.624), and results of specific gravity (dry, wet) of fine aggregate (sand) for samples (1, 2, 3) reached at average (2.56, 2.542) respectively, while a results of samples (4, 5, 6) reached at average (2.491, 2.511), all the results within of limits that allowable according on American designation[2] between (2.3 – 3.2) . The strength tests (California bearing ratio) shows suitability to qualification needs to road works for sub base layer , where the values are (36%), (35%) respectively. Durability geotechnical tests (loss Angeles) results shows the weight loss for samples (1,2,3) are (% 20.4 ,% 25 , % 22.7) respectively, while for samples (4, 5, 6) the result are (19.80%, 22.3%, 20.06%) respectively. The Soundness test results for coarse aggregate (gravel) are (1.236%) for sample (1) and (1.062%) for sample (4) ,while the Soundness test results for fine aggregate (sand) are (2.897%) for sample (1) and (2.717%) for sample (4), so all samples are suitable to use in roads & concrete works .
