| 摘 要： | 用城市生活垃圾焚烧灰渣替代部分集料,按照9种不同的配比制备二灰灰渣碎石路面基层材料,进行路用性能试验。结果表明:与普通二灰碎石对比,在相同的二灰含量下,灰渣碎石的最大干密度降低8.8%,而最佳含水量增大38.4%;无侧限抗压强度最高可达1.03 M Pa;粉煤灰含量对材料强度影响较为显著,其中粉煤灰含量减少1%,无侧限抗压强度值降低21%;材料的干缩系数最大为67.2μ/%;石灰与粉煤灰含量越低,材料的干缩应变越小,平均干缩系数也越小,当二灰含量减少2.5%,平均干缩系数降低3.1%。二灰灰渣碎石材料满足基层的相关要求,灰渣可以为公路建设提供可持续的集料来源。

| Abstract: | By replacing a part of macadam,wastes incineration residues used as aggregates to make lime-fly ash stabilized residues-macadam materials are conducted at nine different proportions.Compaction test,unconfined compressive strength test and shrinkage test are designed to evaluate the pavement performances of the material.Furthermore,the comparative trials are conducted between the new materials and traditional lime-fly ash macadam at the same proportions.Comparing with the traditional lime-fly ash macadam,the... |
