The invention discloses a root expansion deformation regulation and control structure for a highway roadbed pavement in a southern bamboo forest area and a construction method. The structure comprises an asphalt pavement structure, an ecological curb structure and a roadbed slope structure, and the thickness of the asphalt pavement structure is matched with the underground growth depth of bamboo rhizomes; the ecological curb structure comprises a body which is narrow in top and wide in bottom and is integrally in an L shape, an L-shaped through cavity is formed in the body, a water passing channel is formed in the upper surface of a lower body of the body, and the two ends of the water passing channel are through in the length direction of the body; drainage ports are formed in the upper body and the lower body of the body at intervals, the drainage ports are communicated with an L-shaped through cavity, and the L-shaped through cavity is connected with a side ditch at the slope bottom through torrent grooves
