material grade meaning in English
材料级别
Examples
- This is the cement stabilizing material grade design method which has taken account of crack resistance property
据此提出了考虑抗裂性的水泥稳定类材料配合比设计方法。 - Because the best grade limits does not vary with material property , firstly , we can confine material grade to the best grade limits when doing subbase mixture design , secondly , after systematic temperature contraction test , aridity contraction test and compressive strength correction test , we can determine the best cement percentage which has the best crack resistance property
因为最佳级配范围是与粒料的粒径大小有关的，所以在基层材料配合比设计时可首先将材料级配限制在最佳级配范围以内，然后通过系统的温缩、干缩性能试验以及抗压强度校核试验，最终确定抗裂性较好的合理水泥剂量。 - Secondly , making use of the road condition and date of different districts of hebei province , the main diseases of road are analyzed , and combined with the local climate , the factors that cause these diseases are analyzed too . this article discusses the factors , including the quality of asphalt and aggregate , gradation and bituminous quantity , effect on the performance of asphalt mixture . finally , through some new key technical index , including the high - temperature rut resistance , low - temperature crack resistance , and water stability of asphalt pavement , the material types , material grade and pavement structure have been put forward to be fit for asphalt pavements of every area of hebei province
其次，通过对全省各地市的路况、气候等资料进行实地调查，利用收集上来的资料分析河北省的主要道路病害，并结合当地的气候情况，分析病害的主要类型及特征，找出病害的主导因素，并利用一些新的关键性指标(如试验方法、评定指标等)来分析沥青路面的高温抗车辙性、低温抗裂性和水稳定性等沥青结合料和沥青混合料的相关路用性能。
