Utilization of a New by-Product Material for Soft Subgrade ...

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 ...

Subgrade - Pavement Interactive

Subgrade materials are typically characterized by (1) their resistance to deformation under load, in other words, their stiffness or (2) their bearing capacity, in other words, their strength. In general, the more resistant to deformation a subgrade is, the more load it can support before reaching a .

Variable Modulus of Subgrade Reaction - Civil Engineering ...

Nov 03, 2018 · As discussed above, modulus of subgrade reaction is the ratio between the contact pressure (q) and its corresponding settlement (s). For a uniformly loaded flexible foundation, contact pressure remains uniform throughout the foundation, but settlement decreases from the center towards the edge, so q/s or modulus of subgrade reaction increases from the center towards the edge (Figure 2).
