<正>采用双因素方差分析的试验方法,研究了细集料含量和二灰比例双因素对二灰碎石混合料早期强度影响的变化规律,对其显著性进行了分析。结果表明,细集料含量对二灰碎石混合料早期抗压强度有显著影响,并随龄期的增长影响更为显著。

With the wholeinteract test form of twofactor variance analysis,the rule that the content of fine aggregate and the ratio of lime fly ash affect the early compression strength of lime fly ash bound macadam has been studied.The content of the fine aggregate is of an obvious influence on lime fly ash bound macadam’s early compession strength and it will be more obvious with the increasing of the time.During the early period,the ratio of lime fly ash is not of obviously independent influence to lime fly ash bound macadam’s early compression strength.After a certain time,it is by further research,the optimum content of the fine aggregate has been proposed.
