求翻译：本课题做了大量的粗细集料的筛分试验、密度试验，得到集料的密度、吸水率、空隙率等数据。然后拟出级配曲线进行配合比设计，进行马歇尔试验，得出最佳油石比。是什么意思？

Done a lot of the topics the thickness of the aggregate screening test, density tests, density, water absorption, porosity of the aggregate data. Then draw up the grading curve of mix design, the Marshall test, obtained the best aggregate ratio.

This subject has done a lot of weight sets the density of the screening test, Test, and have been set the density, water absorption, and clearance rate, etc. And then the class with the curve for more than design, testing, and Marshall, best oil stone.

This topic has performed the massive thick fine aggregate screening experiment, the density experiment, obtains data and so on aggregate density, water-absorptivity, percentage of voids.Then draws up the grading curve to carry on the mixture ratio design, carries on Marshall to experiment, obtains t

This topic has done a great deal of coarse and fine aggregate screening test, density, receive aggregate data such as density, water absorption, rate of gap. Mix design and prepare gradation curves, Marshall tests, come to the best stone.
