FIELD TRIAL WITH SULPHUR-EXTENDED-ASPHALT (SEA) BINDERS, U.S. RT. 13, GREENWOOD, DELAWARE, A DETAILED DESIGN AND CONSTRUCTION REPORT

This report contains a description of materials, equipment, quality control procedures used during the construction of pavement sections with sulphur-extended-asphalt (SEA) binders. It also highlights design procedures and emissions control monitoring used for the project. The objective is to compare the performance of pavement overlays with SEA binders against those with conventional asphalt binders. The performance of pavement overlays whose SEA binders are formulated with an "in-line blender" before introduction into the pugmill are compared to those whose SEA binders are formulated by mixing sulphur and asphalt in the pugmill. To accomplish the "in-line" blending hot oil heating lines were rerouted from one of the plants asphalt storage tanks to two (2) sulphur storage tanks mounted on an SAE-15 Illusion Blending Unit supplied by Texasgulf Corporation. A line was also connected directly from the blending unit surge tank to the pugmill weight hopper. Actual mixing, transportation and laydown require no different skills than asphalt. But because mixing and laydown temperatures are different, close attention must be paid to temperature control. This project strongly indicates pugmill mixing of sulphur with asphalt is all that is necessary. (FHWA)
