The invention relates to a block stone layer slope protection roadbed with sun shading and ventilation cooling efficacy. The structure of the block stone layer slope protection roadbed is characterized in that block stone layers, earthwork clothes and rammed clays are sequentially laid on embankment slopes respectively; the particle size of the block stone layers is controlled to be 12-30cm, the thickness of each of the block stone layers is 80-120cm, and the void ratio of block stones is 25-30%; and random throwing and extrusion are carried out, and the block stone layers horizontally extend 2.0m width in the slope bottom position to form open boundaries. One earthwork cloth is laid on the slop of each of the block stone layers, clays are laid on the earthwork clothes, and ramming is carried out to realize compactness. The sunshade effect of clay layers is used to weaken the heating effect of sunshine radiation on the slopes of the roadbed; and the slope block stone layers are used to reinforce natural convection and forced convection in cold season block stone layers, so the cold energy suction capacity of the roadbed is improved, and heat in the roadbed is carried away. The heat shielding effect of the block stone layers is used in warm seasons to obstruct invasion of extraneous heat, so the heat suction capacity in the warm seasons is effectively controlled. The block stone layer slope protection roadbed realizes reduction of the temperature of overlaid soil below the slope protection roadbed, and plays a positive and great role in maintenance of long-term stability of several-years frozen soil zone roadbeds.
