Objectives: In this work, the possibility of using crumb rubber powder was an additive to improve the strength of soft soil was investigated. Methods: Two types of problematic clay soils are stabilised with the various percentages of crumb rubber (5, 10, 15 and 20%). The strength properties of stabilized soils were improved by increasing percentages of crumb rubber up to 10% is studied by the CBR tests. In addition to strength development, the influences of this stabilizer type and different quantities on drainage characteristics are also studied. Findings: Addition of crumb rubber in both the soils shows desirable changes in permeability. With the addition of crumb rubber of 10% shows the improvement in CBR value of soil is 161% and 130% in soil A1 and A2. The results obtained shows that both strength and permeability modification results in the better stabilization for clayey soil. Applications: Increase in CBR value of stabilized soil can significantly reduce the overall thickness of the pavement and hence the total cost involved in the construction of road.
