通过室内试验测定不同配比的石灰粉煤灰稳定钢渣土的抗压回弹模量和劈裂强度,并采用路面设计软件BISAR分析底基层层底拉应力的变化规律.研究结果表明：配比中钢渣掺量为40%时的劈裂强度最高,配比中钢渣掺量为70%时的抗压回弹模量最高;随着钢渣掺量的增加,道路基层层底计算拉应力逐渐减小,底基层层底计算拉应力逐渐增大.路面结构设计中选择劈裂强度最高、抗压回弹模量适中的配比,取得较好的效果.

The modulus of compressive resilience and splitting strength of lime-ash soil mixed with steelmaking slag was studied through laboratory test. The change rule of tensile stress at the bottom of base and subbase was analyzed through Bisar software. When the steelmaking slag averages at 40% in the mixture, this formula had the highest splitting strength. When the steelmaking slag averages at about 70% in the mixture, this formula had the highest modulus of compressive resilience. The tensile stress at the bottom of base declines and the tensile stress at the bottom of subbase increases with steelmaking slag content increase in road pavement design. The mixture which had the highest splitting strength and appropriate modulus of compressive resilience could get better design effect.
