Randomized trial investigates improved geotechnical properties of lateritic soil using cow bone ash for road work, suggesting environmental benefits.
Key Points
This research aims to evaluate cow bone ash as a stabilizer to enhance the geotechnical properties of lateritic soil for road construction while addressing environmental pollution.
Collected lateritic soil samples from Peke Airport Road.
Stabilized soil with varying percentages of cow bone ash (0%-10%).
Conducted standard laboratory tests including specific gravity, Atterberg limits, compaction, and California Bearing Ratio.
Unsoaked and soaked California Bearing Ratio increased from 51.0% to 57.0% with 10% cow bone ash.
Atterberg limits showed a reduction in liquid limit from 44.5% to 30.0% with 10% cow bone ash.
Maximum dry density increased from 1660 kg/m³ to 1770 kg/m³ with 10% cow bone ash.
