This report describes the construction of experimental asphalt- rubber and polymer-asphalt open-graded friction course overlays on Interstate 5 in Vancouver, Washington. A 1200 foot section of conventional open-graded pavement was included as a control section. Evaluations will be conducted over a period of three years to measure the performance of the rubber and polymer sections against the control section of conventional open-graded pavement.
Initial observations and tests show no significant differences between the control and the asphalt-rubber and polymer sections.
