THE USE OF SULFUR IN FLEXIBLE PAVEMENT ROAD CONSTRUCTION OPPORTUNITIES AND CONCERNS

Sulfur has been incorporated into asphalt mixture for a number of years in an attempt to combat various damage and failure mechanism that occur in flexible pavements at an increasing rate such as shoving, rutting, and raveling. Furthermore, the cost of road construction materials in particular bitum...
