摘要：
The paper offers an investigation for the viability of basic oxygen furnace slag sludge in asphalt mixture. The sludge has adequate clearance and relatively high Ridgen void. Its zinc element and toxic leachate content meet the requirements for Class III underground water in China. Therefore the BOF sludge is applicable to the filler requirements. Its alkalinity, vesicular texture, and large surface area nature all give contributions to the improvement of road performance for asphalt mixtures. Indirect tensile strength test and three points bending test respectively demonstrate that the BOF sludge added asphalt mixtures show acceptable and better moisture and low temperature crack resistance over the mixtures with limestone powder.
