Post Construction Evaluation of U.S. 69 Sulfur-Extended-Asphalt (SEA) Pavement Test Sections in Lufkin, Texas

摘要

This report deals with the post construction evaluation of an experimental SEA pavement field trial on U.S. 69 north of Lufkin, Texas. The binders used in this field trial consist of pure asphalt cement for the control sections and 30/70 weight percent of sulfur/asphalt in the SEA test binder. All elements of the structural (thickness) design were produced in pairs for comparison of SEA against asphalt sections. Two thinner sections were constructed to possibly show distress in two or three years. Otherwise, the thickness designs used in the test sections were the same as those specified by the Texas State Department of Highways and Public Transportation in the conventional sections of this highway.
