%X Silt soil cannot satisfy the requirements of
highway construction because of its low strength. A new stabilizer from waste
aluminum industry is developed (aluminum chops (AC) and wires (AW)) to evaluate
the effect of reinforcing the subgrade with low-cost by-product materials on
its mechanical and durability characteristics. Laboratory tests, including
modified proctor compaction, compressive strength, splitting tensile
strength, and CBR are developed to evaluate the mechanical properties. The
durability properties are investigated by studying the influence of environmental
conditions such as water immersion effect on compressive strength, mass loss
after freezing and thawing cycles, water absorption by capillarity and wetting-drying
durability. Moreover, a practical application about the base course thickness
saving and
its economically viable as well as cor- relations between mechanical properties are
investigated. The results indicated that the alumin- ium fiber can effectively
improve the mechanical and durability characteristics of silt subgrade where
the increase in aluminum chops grade leads to improve the majority properties.
While aluminum wires of 2.0 cm length produces reduction in CBR and compressive
strength compared to smaller length. Stabilization with aluminium fiber has a
remarkable influence in reducing the base course thickness (especially at using
4% of AW1.0) and increasing the construction cost sav- ing (especially at using
1% of AW1.0).
