| 2. | The force mixes the design that makes up of the broken stone basic unit and construction craft 级配碎石基层的组成设计与施工工艺 |
| 3. | Reason analysis and control of segregation in cement stabilized macadam base course construction 谈水泥稳定级配碎石路面基层施工质量控制 |
| 4. | The asphalt pavement on cement - bound crushed stones base produces cracks easily so that the structure of pavement is destroyed too early 水泥稳定级配碎石基层沥青路面易产生裂缝,造成路面结构过早破坏。 |
| 5. | On the base of a great deal of data fa has been added in to improve road - related performances of the base in the paper 本文在大量实测调查资料的基础上,兼顾推广的要求,采用掺加粉煤灰的方式,改善水泥稳定级配碎石基层的路用性能。 |
| 6. | Basing on it . make a possiblecombination about material ' s thickness and module to predict it ' s compacity to outside load . it can do some work for design of pavement structure 本文还研究了级配碎石路面各结构层的厚度、模量参数组合对于外界各类荷载承受能力,为路面结构方面设计提供一些参考数据。 |
| 7. | About mixture rate of calcium carbide dust stabilization and calcium carbide dust s mixing dose , controlling methodand construct technics , we conduct large number of indoor tests and outdoor tests and educe scientific datas and methods 对于电石灰稳定土、电石灰二灰土和电石灰二灰稳定级配碎石的配合比以及电石灰的掺和剂量、控制方法、施工操作工艺等都做了大量的室内、室外试验,得出比较科学的数据和方法。 |
| 8. | We can use both calcium carbide dust and calcium carbide dust - flyash to stabilize fine - soil . as well as being used in subbase of high grade road , calcium carbide dust stabilization and calcium carbide dust - flyash stabilization can be used in basecourse of low grade road . so we can deduce that calcium carbide dust - flyash - gravel stabilization can be used in basecourse of high grade road 我们可以利用电石灰来稳定细粒土,利用电石灰和粉煤灰来稳定细粒土。通过数据分析,这种电石灰稳定土和电石灰二灰土完全可以刚于高等级公路的高级路面的底基层,也可以用于低等级公路的路面基层,同时推断,用电石灰和粉煤灰来稳定的级配碎石,可用于高等级公路的路面基层。 |
| 9. | By a great number of tests indoors , the theoretic analysis of microstructure and fracture mechanics , tests on the test - road , after the analysis of road - related performances of cement - bound crushed stones base and the study for improvement , the conclusion is put forward , that applying the cement fa - bound crushed stones base can obviously minish the maximal stress of asphalt pavement , lighten and stay cracks in the asphalt pavement effectively and economically so as to improve long - term performances of the structure of pavement 通过大量室内试验、微观结构和断裂力学理论分析,铺筑试验路段现场检测,分析水泥稳定级配碎石基层的路用结构性能,并研究其路用性能的改善措施,得出水泥粉煤灰稳定级配碎石基层可明显减小沥青面层的最大应力,经济有效的减轻和延缓沥青路面开裂,改善路面结构长期使用性能。 |
| 10. | Calcium carbide dust pollutes environment seriously and in addition , the question of storage restricted the development of the corporation . to settle the question about calcium carbide dust is imperative under the situations . the text expatiated the application of calcium carbide ash in highway building . the article includes five aspects : 1 . application of lime soil 本文主要阐述电石灰在公路工程中的应用,为说明问题,全文共分五个部分,即一、石灰土在公路工程中的应用;二、二灰土的应用;三、石灰粉煤灰稳定级配碎石;四、电石灰应用;五、对沧州地区柔性路面结构组合的建议。 |
