Abstract
This research included the geotechnical assessment of the compact gravel of the Tuz- Chai River / Salahaddin Governorate / Iraq. The results of the evaluation showed the natural accumulation of the Tuz- Chai River sediments, which are geologically belonging to Quaternary deposits and its suitability for use in the road works.
This evaluation showed the possibility of the use of the untreated pebbles of the Tuz- Chai River in the road works for sub base layer (type A, B and C). It can also can be used to produce asphalt-fixed gravel and sand for roadwork construction and for asphaltic base layer.
