Low able fill material is a self – leveling– compacting one; these types of material rapidly gain acceptance and application in construction utility earthworks. The use of scrap tires as a reinforcement element is an attractive solution that combines theadvantage of improving soil mechanical behavior with environmental concerns. The present work describes an experimental study on replacing sand aggregate grain size with wastes rubber and plastics at different mixing ratio (6, 18, 30) % wt. respectively to support technical feasibility of muddy soil by using wastes materials then compared with commercial additives (carbon fiber) afterward check their hydrodynamicalproperties (E.L, P.L, hydrometer, compaction, and sp.gr) of preparedcompacting improved soil mixtures. Experimental results indicate that crumb rubber have successfully used to produce a light weight flow able fill ( 1.2 to 1.6 g/ cm3 ) than other additive waste plastic and carbon fiber based on the characteristic properties (E.L, P.L, hydrometer, compaction ) as follows: Have 65% for rubber samples than other additives of 45% and 55% molecules respectively for hydrometer test, 2 Gs for rubber than 1Gs for other additives; and 560 g/cm3 compaction for rubber additive than 520 g/cm3 for other additives carbon fiber and waste plastic.
