摘要 To determine the modification mechanism of Trinidad Lake asphalt, ash was isolated for microscopic property testing, technical index analysis, and research on ash interaction with asphalt, Ash was compared with two types of filler. Based on the separation effect and operational feasibility, the use of centrifugation for ash separation is better than the other methods. The test of microscopic particle morphology and the crystals reveal the small size and rough surface structure of ash. Ash is mainly composed of quartz and clay and exhibits large density, fine granularity and a large specific surface area. The G^*/sinδ of ash mortar shows that ash reinforces stiffness better than that two kinds of filler. When the ratio of filler binder exceeds 1.2, the growing rate is larger than that of ordinary filler. Thus, ash could enhance the high-temperature performance and strength of asphalt owing to its small size, large surface area, and rough surface.

Abstract：To determine the modification mechanism of Trinidad Lake asphalt, ash was isolated for microscopic property testing, technical index analysis, and research on ash interaction with asphalt, Ash was compared with two types of filler. Based on the separation effect and operational feasibility, the use of centrifugation for ash separation is better than the other methods. The test of microscopic particle morphology and the crystals reveal the small size and rough surface structure of ash. Ash is mainly composed of quartz and clay and exhibits large density, fine granularity and a large specific surface area. The G^*/sinδ of ash mortar shows that ash reinforces stiffness better than that two kinds of filler. When the ratio of filler binder exceeds 1.2, the growing rate is larger than that of ordinary filler. Thus, ash could enhance the high-temperature performance and strength of asphalt owing to its small size, large surface area, and rough surface.
