Description:DuraFlex Curb, an erosion control alternate for timber, concrete, or bituminous curbing placed with guardrail, has been submitted for consideration for the CDOT Approved Products List (APL). DuraFlex Curb is made of HDPE in an "L-shape." The vertical arm of the "L" provides a six-inch high vertical section placed at the face of the guardrail posts. The eighteen-inch wide horizontal arm sits flat on the existing pavement and is overlaid with hot mix asphalt. Projects on US-24 in Region 2 and on US-50 in Region 5 were selected for evaluation. On US-24 approximately one thousand feet of the DuraFlex Curb were placed in two 500' test sections. On US-50 approximately two thousand feet of DuraFlex Curb were installed. On the US-50 project approximately seven thousand feet of composite lumber curb were installed for evaluation also. This report evaluates the performance of the two products in comparison to lumber curb.
