SULPHUR/ASPHALT MIXTURE DESIGN AND CONSTRUCTION DETAILS-- LUFKIN FIELD TRIALS

The introduction of elemental sulphur as a binder in paving mixtures has been under study for several years in Canada and Europe. The use of elemental sulphur in flexible pavements of the United States is a recent affair sponsored initially by the Sulphur Institute and the U.S. Bureau of Mines. This report deals with pavement mixture designs and construction operations of field trials on U.S. 69 north of Lufkin, Texas. The binders used in this field trial consisted of pure asphalt cement for the control sections and 30/70 weight percent of sulphur/asphalt emulsion as the test binder. All elements of the structural (thickness) design were produced in pairs for comparison purposes with the exception of two thinner sections selected to possibly show distress in two to three years. Otherwise, the thickness designs used in the test sections were those specified by the State Department of Highways and Public Transportation in the conventional section of this highway. Preconstruction laboratory evaluations of mixture properties and field laboratory control measurements are included as a part of this report. Construction operations are detailed by photographs and verbal descriptions.
