Abstract

Ferrous-nickel slag is an industrial waste material which produced from smelting process of ferrous-nickel uses in manufacturing of stainless steel and ferrous alloy industry, in China Guangdong province itself, it was estimated around 6-7million of ferrous-nickel slag has been produces annually, the common method in order to reutilize ferrous-nickel slag material is by using on cement industry (replace cement material) and as land-filling material. One of the main objectives of this study is to investigate the feasibility of reutilization of ferrous-nickel slag combined with soil improvement method to portion replace conventional construction materials such as sand and granular material on sub-grade or sub-base layer of pavement construction. Strength and swelling properties of ferrous-nickel slag and soil (sand) mixture after treatment with soil improvement agent will be use as main consideration the performances of ferrous-slag nickel material on road construction, includes 4-days soaked California Bearing Ratio (CBR), 7-day Unconfined Compressive Strength (UCS) and also swelling behaviour of the mixture.
