【摘要】 抗拉强度是二灰碎石的主要力学性能之一。研究表明，集料级配、集料最大粒径、养生条件和龄期对二灰碎石的劈裂抗拉强度有很大影响。最大粒径愈小、颗粒愈细，二灰碎石的劈裂抗拉强度就越高；二灰碎石的劈裂抗拉强度随养生温度的提高或龄期的增长而提高。更多还原

【Abstract】 Tensile strength is one of main mechanics properties of lime-fly ash hound macadam. There are indications from experiment and study that aggregate grading, maximum particle size of aggregate, curing condition and age markedly influence splitting tensile strength of lime-fly ash bound macadam. The smaller maximum particle size of aggregate is or the finer grain is, the larger value of splitting ten- sile strength of lime-fly ash bound macadam is. The value of splitting tensile strength of lime-fly ash bound macadam increases when curing temperature or age increases.更多还原
