路基的强度和稳定性，取决于土的工程性质，并要与填土的高度和施工技术相关

路基的强度和稳定性，取决于土的工程性质，并要与填土的高度和施工技术相关。所以选择合适的路基填土对于整个道路的稳定性与耐久至关重要。
(1)路床填料最大粒径应该小于100mm，路堤填料的最大粒径应小于150mm。
(2)采用细粒土填筑路基时，填料的最小强度应满足表2的要求，当不能满足要求时，可以掺石灰或其它稳定材料处理。
(3)浸水路堤应选用渗水性良好的材料来填筑。当采用细砂、粉砂作为填料时，应考虑振液化的影响。
(4)采用粉煤灰填筑路基时，应预先调查材料来源并做好必要的室内试验。
路基填料最小强度要求如表2所示

結果 (英文) 1:

The strength and stability of the embankment, depending on the engineering properties of soils and associated with the fill height and construction technology. So choose the right Foundation fill for the road of stability and durability is essential.(1) road-packing maximum size should be less than 100mm, embankment fill shall have a maximum particle size of less than 150mm.(2) when using fine grained soil subgrade filler should meet the minimum strength requirements of table 2, when you can not meet the requirements, can be mixed with lime or other material handling.(3) of soaking embankment good porous material should be used to fill. When using fine sand, silty sand as a filler, should consider the influence of vibrating liquefaction.(4) when using fly ash subgrade should investigate the source material in advance and make the necessary laboratory tests.Minimum strength requirement subgrade as shown in table 2

結果 (英文) 2:

The strength and stability of the roadbed, depending on the engineering properties of soil, and to the height and construction techniques associated with the filling. So choose the right embankment construction is crucial for the stability and durability of the entire road.
(1) road bed packing maximum particle size should be less than 100mm, the maximum particle size should be less than filling embankment 150mm.
(2) the use of fine-grained soil to fill roadbed, the minimum strength filler should meet the requirements of Table 2, when you can not meet the requirements, can be mixed with lime or other stabilizing material handling.
(3) should be used in water seepage flooding embankment with good filling material. When using sand, silt as a filler, it should consider the impact of vibration liquefaction.
(4) When filling fly ash embankment, should investigate the source material in advance and make the necessary laboratory tests.
Roadbed filler minimum strength requirements shown in Table 2

結果 (英文) 3:

The strength and stability of subgrade depends on the engineering properties of the soil, and it is related to the height of the soil and the construction technology. So it is very important for the stability and durability of the whole road to choose the suitable roadbed fill.(1) the roadbed filler maximum diameter should be less than 100mm, the embankment should be less than the maximum diameter of 150mm.(2) the fine grained soil filling road base, the minimum strength of packing should meet the requirements of Table 2, when can not meet the requirements, can be mixed with lime or other stable material processing.(3) the water permeability of the embankment should be used to fill the water permeability of the material. When the fine sand and silt are used as fillers, the influence of vibration should be considered.(4) when the fly ash is used for filling the subgrade, the source of the material should be investigated in advance and the necessary laboratory tests should be made.The minimum strength requirement of subgrade filler is shown in Table 2
