Road base is the Foundation of pave

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.

路基路面是的基金会，它是根据重量和土壤本身的路面结构的重心，同时还通过痛苦的道路交通负荷传下来的，所以路基路面轴承为主。
（1）设计，不应该注重协调与自然环境和城市景观一直以来，充分考虑沿线地质和水文特色的道路，在有效利用原有的，切割和线程平衡，尽量避免高挖。
（2）占用应与土方和路基的石雕城市地方规划相结合，考虑到土壤类型，地球，土地和运输条件等因素，选择提取，废弃的场地之一。
（3）路基设计哈德发誓因地制宜，合理利用当地的材料，工业和建筑垃圾废物。固体废物欧盟不能用于灌装。
（4）路基的设计应考虑到在路上跑充分考虑不利的各种因素，减少可变性，确保持久耐用。
（5）顶部的道路横坡和路拱应该是一致的横坡。
（6）路包装应均匀，致密，最大和最小尺寸的围巾符合相关的强度要求。
（7）路基处理措施应根据土壤，降水，地下水和深度，增强材料的来源，比较和相应的施工方法的选择。
（8）设计原则：必须是紧凑堤，均匀和稳定的。道路路基谷底回弹模量值的底部设计应大于或等于到20MP。特殊情况下，可能会发誓下面为15Mpa。它不符合上述不应该采取相应的要求，提高土体强度的基础措施。设计应因地制宜，合理利用当地的材料和工业废物的线。对于堤特殊的地质和水文条件下，按相关标准设计应与本土经验相结合。合理利用当地的材料和工业废物。对于堤特殊的地质和水文条件下，按相关标准设计应与本土经验相结合。合理利用当地的材料和工业废物。对于堤特殊的地质和水文条件下，按相关标准设计应与本土经验相结合。
