Abstract

An impact recovery delineation system comprises a base member that provides improved mechanical and chemical bonding to the road surface and a portable base that provides a rigid center portion and flexible ends to maintain the position of the delineator device after vehicle impact. A sealed, pneumatic tube of high impact resistant material composition acts as a delineator post and is adapted to receive modified load cells. Upper and lower load cell elements are provided with cable passages to allow side-by-side placement of wire rope cables. The passages are particularly geometrically configured and have two radiused edges and two straight edges which result in rapid bending and recovery of the delineator post system upon high speed impact, in any direction, by an automotive vehicle. A vented signage panel having air vents therein to reduce wind resistance, improve and speed recovery of the impacted system. A safety loop in the cable system is provided to prevent the delineator post and signage from being separated from the load cell abutment base connection should there be a structural failure at this connection. A flexible portable base structure is provided for temporary location of delineation posts and which is provided with an intermediate stiffener and flexible weighted ends to prevent its lifting from the roadway upon vehicle impact with the impact recovery delineator post system supported thereby.
