maximum grain size meaning in Chinese

最大粒径

This paper conbined with the indoor test and the scene test road , through the synthetical analysis of the factors of influencing densification effect for the densification thickness of filling stone roadbed . the maximum grain size of fill material , densification machinery and densification frequency et al . advanced a control norm of the maximum grain size and piy of compression , established ration evaluating the control standard of densification quality of filling stone roadbed under overload . comparing with result of indoor test and the scene test road , studied on theory of densification in different kinds of stone material and perfected the control system of the densification of filling stone roadbed under overload
结合室内试验和现场试验路的实测数据，通过对填石路基的压实厚度，填料最大粒径，压实机械及压实遍数等影响压实效果的因素的综合分析，提出填石路基的最大粒径和摊铺厚度的控制指标，建立定量评定超重载交通下填石路基压实质量的控制标准，并对照室内试验和现场试验结果，研究不同石料条件下的压实理论，补充完善了填石路基压实控制指标体系。
