The invention discloses a road buffering guardrail. The road buffering guardrail comprises a guardrail column and a guardrail plate; the guardrail column is a hollow pipe body, and a groove hole is formed in the part, close to the guardrail plate, of the guardrail column; a mounting plate is fixedly arranged in the guardrail column, and a buffering device is fixedly arranged on the mounting plate;the buffering device comprises a sliding seat, a slideway is formed in the sliding seat, one end of the slideway is open, and the other end of the slideway is closed; the open end of the slideway directly faces the groove hole; the slideway is internally provided with a first magnet which can slide along the slideway and a fixed second magnet, and the first magnet and the second magnet are mutually repelled when the first magnet and the second magnet are close to each other in the slideway; the first magnet is close to the open end of the slideway, a pushing rod is horizontally arranged, oneend of the pushing rod is fixedly connected with the guardrail plate, and the other end of the pushing rod is in pivot connection the first magnet; and the pushing rod penetrates through the groove hole and the open end of the slideway. According to the road buffering guardrail, the energy absorbing effect is high, the buffering effect is good, and the guardrail plate is not easily damaged by impact.
