Sulfur Extended Asphalt Pavement Evaluation in the State of Washington: SR 270 Highway Pavement Performance Report

This report summarizes the placement and performance of sulfur extended asphalt (SEA) paving mixtures at a highway test site (SR 270) near Pullman, Washington. The report includes a summary of the mixture and structural designs and construction details. This is followed by a discussion of the data collection and analysis accomplished over a three year evaluation period (1979-1982). A major experimental feature of the study was the use of 0/100 (conventional asphalt concrete), 30/70 and 40/60 SEA binder ratios (sulfur/asphalt ratios are expressed as weight percents) in the experimental paving mixtures.
