The invention relates to the technical field of road engineering, in particular to a longest catchment path-based arrangement method of a highway ultrahigh mitigation section drainage system, which comprises the following steps of: performing field investigation; simplifying the maximum catchment path into a plane quadratic curve, and establishing a plane coordinate system by taking a point where the maximum catchment path enters the ponding area as an original point O, taking the direction of a path center line of the point O as an X axis and taking the direction of a vertical path center line as a Y axis; determining the position of a starting point A of the maximum catchment path; deducing a quadratic curve of the maximum catchment path according to the coordinates of the point A and the point O and the derivative of the maximum catchment path curve at the point O; and determining the number of the intercepting grooves according to the longest catchment path and determining the setting angles of the interc
