摘要：

The Phosphorus Slag (PS) is a yellow phosphorus industry by-product which could lead to land and water pollutions if not properly processed, researchers have found that the PS micropowder can be used as an additive for asphalt pavement applications. However, the difference in surface properties of PS micropowder could result in the variation of pavement performances. This research carried out the PS surface modification technique and evaluated the optimum surface modifier among five different types of modifiers and analyzed the optimum modification time, temperature and content of PS additives...
