摘要
A method of making a sulfur-extended asphalt mixture with a minimum of hydrogen sulfide gas release into the atmosphere by using sulfur granules with specific physical properties and which are made by successively coating a starting sulfur seed particle with liquid sulfur that is solidified between coatings to thereby build up the a sulfur particle of a desired size.
