Therefore, recycling or reusing them are the preferred options for sustainable development. The study presented the use of incinerated sewage sludge ash (ISSA) as a soil stabilizing agent. Oxide compositions were determined by the X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD) and Toxicity Characteristic Leaching Procedure (TCLP). Result showed that ISSA contains Silicon oxide, SiO2 (61.42 %), Aluminum oxide Al2O3 (23.51 %) and Iron oxide, Fe2O3 (4.24 %) in high proportion. Clay soil with low to medium plasticity (CL) from an A-7-6 group was replaced with 0 % 3 %, 5 %, 7 % and 10 % ISSA. Test such as California Bearing Ratio (CBR), Unconfined Compressive Strength (UCS), Compaction and Atterberg limit were conducted. Soil obtained lowest OMC and highest MDD values both at 7% ash conten...
