The I-80 Donner Pass job was a watershed in the history of polyester-styrene polymer concrete highway overlay; the culmination of approximately ten year’s research and test jobs by Cal-Trans. Completed in 1986, the lo-lane-mile job was highly successful. This paper reviews criteria used to select the overlay chemistry, procedures, equipment and suppliers used in the job; as well as the 1988 review by the senior materials and research engineer. The paper includes nine-year wear data by Cal-Trans and a look forward by individuals currently involved in on-going overlay projects being specified by Cal-Trans. Based on the success of this l-80 job, Cal-Trans continues to specify polyester-styrene polymer concrete for bridge decks and highway overlays.
