This report summarizes the placement of sulfur extended asphalt (SEA) paving mixtures at two test sites near Pullman, Washington. One site was on an existing state highway and the other made use of the Washington State University Test Track. The report includes the preliminary mix designs, pavement thickness determination, construction details and initial performance data for the test pavements. A major experimental feature of the study was the use of 0/100 (conventional asphalt concrete), 30/70 and 40/60 SEA binder ratios in the experimental paving mixtures.
