Abstract:
1. A Performance Grade sulfur-extended asphalt binder emulsion comprising: a viscosifier in a range of from 0.1% to 3% by total weight of the emulsion; an emulsifier in a range of from 0.1% to 5% by total weight of the emulsion; a base aqueous solution in a range of from 21.7% to 89.8% by total weight of the emulsion; and a Performance Grade sulfur-extended asphalt binder in a range of from 10% to 70% by total weight of the emulsion, where the Performance Grade sulfur-extended asphalt binder comprises a free sulfur in a range of from 10% to 50%, a linear alkane material in a range of from 0.1% to 5%, and a base asphalt in a range of from 38% to 89.9% by total weight of the Performance Grade sulfur-extended asphalt binder, where the Performance Grade sulfur-extended asphalt binder is a Performance Grade asphalt binder per AASHTO Performance Graded Asphalt Binder Specification M 320-10; where the Performance Grade sulfur-extended asphalt binder emulsion has a storage stability of at least 3 hours as determined using the ASTM D 244 testing method.
