Use of scoria waste as subbase stabilization material for highway flexible pavement

Usability of scoria waste as subbase stabilization material was investigated. Initially, the physical properties were examined. The usage in layer pavement In study, experimental researches such stability to freeze, solidity, strength, Atterberg limits and California Bearing Ratio tests carried out on samples prepared by using waste. Scoria natural quarry materials blended different amounts prove percentage plastic limit. Then, limit mixtures. strength obtained reusable determined with (CBR) test. According results, it observed that wastes flexible pavements is appropriate. Moreover, mechanical has positive impact increasing new mixed composite material.
