Abstract
Increasing production of aluminium dross (AD) is posing disposal problems, causing serious pollution. In this study, the effectiveness of this material and hydrated lime (HL) in enhancing geotechnical features of A-7-6 and CH classified soil was evaluated. The soil was admixed with 0-20 % AD and 0-9 % HL by mass of the soil, various geotechnical tests were conducted on soil specimens. A combined mixture of 6 - 9 %HL and 20 %AD that achieved results which fall within the minimum UCS of 0.75 - 1.5 MPa specified for sub-base layer of medium to heavy traffic roads is recommended for strength enhancement of the A-7-6 soil.
