This study examines the effect of partially replacing cement with bluegumwood ash (BGWA) in stabilizing laterite soil to be used as a potential roadbase material. Initially, Ordinary Portland Cement was introduced to the soilat varying contents from 0 to 12% in steps of 3% by weight of the soil sample.Each wet sample of the soil was subjected to the Californian bearing ratio(CBR) and unconfined compressive strength (UCS) tests in determining theoptimal soil-cement mix. Results show that CBR and UCS values increased ascement content increased, and a 6% cement content corresponding to a UCS valueof 2.88 MPa at 7 days of curing met the specifications of the Overseas RoadNote 31 to be used in the construction of road bases. The second treatmentinvolved partially replacing the 6% cement content with BGWA in decreasingsteps of 1%. Peak CBR value of 348% at 2% BGWA content (>160% recommended byKenya road design manual) and UCS value of 2.99 MPa at 7 days of curing wereobtained. Thus, BGWA can partially replace cement in stabilizing laterite soilfor use in the construction of road bases as per the Overseas Road Note 31specifications.
