石灰岩沥青砼路面芯样马歇尔试验研究

Research on marshall testing result of bitumen mixture's Surface drilling core sampling

沥青路面芯样马歇尔试验是检验其路面质量非常关键的方法,但却没有相应的检验标准.笔者依据大量的钻芯芯样的马歇尔试验结果,利用数理统计分析方法,对石灰岩沥青砼的钻芯取样马歇尔试验结果进行了比较详细系统的分析,并研究了沥青砼各性能参数对试验结果的影响,提出了沥青路面芯样马歇尔试验结果的评价方法,并对芯样马歇尔试验结果作出了合理的解释.

Marshall testing of bitumen mixtures surface drilling core sampling is a method that judges the quality of bitumen mixture,but there is no standard.In the paper,mass of drilling core testing results,and making use of statistical analytic methods,we analyse systemically the drilling cores Marshall testing result of limestones asphalt concert,and study the fluency testing results on the performance parameters of the asphalt concert.It presents the method of judging the quality of bitumen mixture,and explains Marshall testing result of bitumen mixtures surface drilling core sampling.
