Examples
- Road materials . test method for the analysis of bituminous mixtures by ignition
道路材料.点火分析沥青混合物的试验方法 - Road materials - test method for the analysis of bituminous mixtures by ignition
道路材料.对沥青混合物进行分析的灼烧试验方法 - The asphalt road materials development have been droved by the development of highway construction , so the quantity and the quality of asphalt materials increase progressively , especially , the demand for performance of weighty traffic asphalt is further high , our country must energetically study and empolder modified asphalt materials for highway construction because of performance of homemade asphalt
公路建设的飞速发展带动了沥青路面材料的发展，与之伴随的对沥青材料的数量逐步增多，而对其质量要求也越来越高，尤其对高等级公路建设所需的重交沥青性能要求更高，由于国产沥青的性能因素决定我国必须大力研究开发能够满足高等级公路建设的改性沥青材料。 - The study solves engineering problem as follows : ( 1 ) the systematic study on the historical course of xigeda strata deposit and geologic environment includes strata , lithologic characters and constitution et in the liangshan and panzhihua region . the results show that the xichang - panzhihua express way is controlled by the anninghe fault and the xigeda fault , the earthquake frequently happen in the region of pass , the different sedimentation number is more great , they effect the road building , safety in operation and structure belong road ( 2 ) because in some place the xigeda strata is foundation and roadbed , the study on the basic properties of the xigeda strata include density , moisture content plastic and liquid limit graduation . the results show that the xigeda strata is deposition in lake , the main component is mudstone and sandstone , the fine particle is main , it has some viscosity , the moisture content of mudstone is different the it of sandstone , the other property are likeness . the xigeda strata has no dilatation on total , some claystone have low and medium dilatation ; ( 3 ) the study on the basic properties of xigeda filler include the composition of matter the biggest standard dry density , , the optimum moisture content the results show that xigeda filler can use as road material , it is well grade filler and admixture filler on essence , its compaction index should change in different place because the property is controlled by mudstone and sandstone that change is great in different place ; ( 4 ) the study on the xigeda filler craft used as express way roadbed , includes suitable thickness , compaction numbers and methods and equipment choice et
公路沿线广泛分布有昔格达地层，昔格达地层能否用作高速公路路基填料，国内没有先例，本论文就是结合导师的科研项目，在非典期间，现场长达5个月的工作，完成了从试验、现场施工工艺到路堤分层沉降监测等工作，是面对生产实际，认识昔格达地层的性质和其作为地基、路基和填料应用中面临的问题进行的研究。主要的研究内容有：对攀西地区地层岩性、构造等地质环境和昔格达地层的沉积历史过程作了系统的分析，研究表明西攀高速公路主要受安宁河断裂和昔格达断裂影响，通过地区地震活动频繁，差异沉降较大，对公路建设、安全运行和沿线构筑物设计有较大影响；由于昔格达地层在有些路段作为地基、有些作为路基，对其基本性质进行了研究：包括天然密度、含水量、塑液限、颗粒级配等指标的试验研究。研究成果表明：昔格达地层为湖相沉积，主要为砂岩和泥岩，它以细粒组为主，同时粘粒的存在，使其具有一定粘性。
