道路路基是路面的基础，它承受着土体本身的自重和路面结构的重力，同时还承受着由路面传递下来的行车荷载，所以路基是道路的承重主体。
(1)路基设计应注意要与沿线自然环境和城市景观相协调，并且充分考虑道路沿线的地质和水文特点，有效利用原有地形，尽量做到填挖平衡，以避免高填深挖。
(2)路基土石方的借弃应结合当地城市规划，兼顾土质类型、土石方量、用地情况以及运输条件等等因素，合理选择取、弃的地点。
(3)路基设计应该因地制宜，合理利用当地材料、工业废料和建筑渣土。生活垃圾不能够用于路基填筑。
(4)路基设计应充分的考虑道路运行中的各种不利因素，减小变异性，保证耐久性。
(5)路床顶面横坡应与路拱横坡应一致。
(6)路床填料应均匀、密实，最大粒径和最低强度应满足相关规范要求。
(7)路床处治措施应根据土质、降水量、地下水类型及埋藏深度、加固材料来源等，经比选采用合适的施工方法。
(8)路基设计原则：路基必须密实、均匀、稳定。路槽底面土基设计回弹模量值宜大于或等于20Mpa。特殊情况不得小于15Mpa。不能满足上述要求时应采取相应措施提高土基强度。路基设计应因地制宜，合理利用当地材料与工业废料。对于特殊地质、水文条件的路基，应结合当地经验按有关规范设计。

Road base is the Foundation of pavement, it is under weight and gravity of the pavement structure of the soil itself, while also suffering passed down by the road traffic load, so the roadbed is a road bearing the main.(1) the design should pay attention to coordination with the natural environment and the urban landscape along, and fully consider the road along the geologic and hydrologic characteristics, effective use of original, cut and fill balance as far as possible, to avoid the high digging.(2) take up should be combined with local urban planning of earthwork and stonework of subgrade, taking into account the type of soil, Earth, land and transport conditions, among other factors, selection extraction, abandoned sites.(3) the roadbed design had to be adapted to local conditions and rational use of local materials, industrial waste and construction waste. Solid waste cannot be used for filling.(4) design of subgrade should be fully taken into account various unfavorable factors in road running, reduce the variability to ensure durability.(5) the road-cross slope and road humps on the top cross slope should be consistent.(6) road-packing should be uniform, dense, maximum size and minimum strength shall meet the relevant requirements.(7) the road bed treatment measures should be based on the soil, precipitation, ground water and the depth, reinforcing material sources, comparison and selection of the appropriate construction methods.(8) design principles: embankment must be compact, uniform and stable. Roads trough bottom design of subgrade resilient modulus values should be greater than or equal to 20Mpa. Exceptional circumstances may be below 15Mpa. Does not meet the above requirements should take corresponding measures to improve the soil base strength. Design should be in line with local conditions, the rational use of local materials and industrial waste. For special geological and hydrological condition of embankment, according to relevant standard design should be combined with local experience.

Road embankment is the basis of the road, which bear the weight of the soil itself and gravity of the pavement structure, but also bear down delivered by road traffic loads, so the roadbed is bearing the main roads.
(1) should pay attention to the design of embankment along in harmony with the natural environment and the urban landscape, and fully consider the geological and hydrological characteristics along the road, the effective use of the existing terrain, try to make the cut to fill the balance, in order to avoid high filling and deep.
(2) should be abandoned roadbed earthwork by combining local urban planning, taking into account the soil type, earthwork, land use as well as transport conditions, among other factors, a reasonable choice to take, abandoned place.
(3) foundation design should be adapted to local conditions, the rational use of local materials, industrial waste and construction waste. Garbage can not be used for roadbed filling.
(4) should be fully taken into account the design of embankment road running various unfavorable factors, reduce variability, to ensure durability.
(5) the top surface of the road bed transverse slope should crown transverse slope should be consistent.
(6) the roadbed filler should be uniform, dense, maximum particle size and minimum strength should meet the relevant regulatory requirements.
(7) Treatment road bed construction methods appropriate measures should be based on soil, rainfall, groundwater type and burial depth, reinforcement materials and other sources through the use of comparison.
(8) roadbed design principles: roadbed must be dense, uniform and stable. Road surface soil bottom base design resilient modulus values should be greater than or equal to 20Mpa. Special case not less than 15Mpa. We can not meet the above requirements should take appropriate measures to improve the subgrade strength. Roadbed design should be adapted to local conditions, the rational use of local materials and industrial waste. For roadbed special geological, hydrological conditions, should be combined with local experience in accordance with the relevant design specification.
