摘　　要：为能通过沥青混合料马歇尔试验结果更准确地获取当前混合料各参数的代表值,提出基于各参数分布规律的控制指标,以此进行沥青混合料的质量控制,基于统计学规律,探索了沥青混合料参数检验评定新方法,首先引入t检验方法对试验结果进行可疑值的剔除,其次提出参数均值及极值的控制标准,并选取实际数据进行了验证。结果表明:所采用的检验评定方法能进行沥青混合料各参数的检验评定。In order to accurately obtain the representative value of each mixture parameter through the Marshall test results of asphalt mixture, the article proposes the control index based on the distribution of each parameter so as to carry out quality control of asphalt mixture. Based on the statistics law, the article explores the new methods of inspection and assessment of asphalt mixture. The t-inspection method is introduced to exclude the questionable value from the test result. The control standards of mean and extreme parameters are proposed. The actual data is selected to verify. The results show that all used inspection and assessment methods can inspect and assess each parameter of asphalt mixture.
