摘　　要：通过击实试验、无侧限抗压强度试验和水稳性试验研究了水泥、粉煤灰掺量对含油污泥热解残渣路基材料性能的影响。结果表明:随水泥、粉煤灰掺量的增加,最大干密度和最佳含水量均减小。含油污泥热解残渣路基材料的无侧限抗压强度随水泥掺量的增加而增大,考虑经济性和强度值,选择水泥掺量为4%制备路基材料。随粉煤灰掺量的增加(10%~30%),无侧限抗压强度先增大后减小,粉煤灰掺量存在最优值(20%)。含油污泥热解残渣路基材料的水稳系数随水泥掺量和龄期的增加而增大。The effect of cement and fly ash on the performance of roadbed materials of pyrolysis residue of oily sludge was studied by the compaction test,unconfined compression strength( UCS) test and water stability performance test. The results show that the maximum dry density and optimum water content decrease with the increase of cement and fly ash. The UCS value of roadbed materials made from pyrolysis residue of oily sludge increases with the increase of the cement content. Considering the economic issue and strength performance,the cement content is selected as 4% for the roadbed materials preparation. With the increase of fly ash content( 10%-30%),the UCS value first increases and then decreases,and the optimum amount of fly ash is 20%. The water stability coefficient of roadbed materials made from pyrolysis residue of oily sludge increases with the increase of cement content and curing age as well.
