The invention discloses a bridge head highway subgrade structure which comprises a subgrade body, a composite protective cushion layer arranged in the subgrade body, a bearing surface layer arranged on the upper surface of the subgrade body and provided with curbstone bonding parts at the two ends, a stone cushion layer arranged under the composite protective cushion layer and provided with a stone wrapping protective layer on the outer surface, and a concrete cushion layer arranged between the bearing surface layer and the stone cushion layer; and a dense cushion layer is arranged on the surface of the lower end of the concrete cushion layer. The subgrade is good in bearing stability and not prone to being affected by the external environment temperature, so that the problems that the subgrade is prone to being damaged and needs to be maintained frequently are effectively solved, a good waterproof effect is achieved, and rainwater is prevented from leaking from the upper surface of asubgrade body to damp a bottom stone cushion layer; meanwhile, a heat insulation cushion layer has a good heat insulation protection effect, and the influence of the temperature difference between summer and winter on excessive thermal expansion and cold contraction of the subgrade body is prevented.
本发明公开了一种桥头公路路基结构，包括：路基主体，以及设置在所述路基主体内部的复合保护垫层；承载面层，其设置在所述路基主体的上表面，且承载面层的两端设置有路牙粘合部；石材垫层，其设置在所述复合保护垫层的正下方，石材垫层的外表面设有石材包裹保护层；混凝土垫层，其设置在所述承载面层和石材垫层的中间，混凝土垫层的下端表面设置有密实垫层。其实现了路基承载稳定性好，不易遭受外界环境温度影响，从而有效的避免了路基易遭受损坏，需要经常维护的问题，具备良好的隔水作用，防止雨水从路基主体上表面渗漏下来导致底部石材垫层受潮，同时隔温垫层具备良好的隔温保护效果，防止夏季和冬季温差对路基主体造成过大热胀冷缩的影响。
