摘要
在乳化沥青稀浆封层混合料中掺加2‰聚丙烯纤维,用水量略有增加,但对初凝时间无影响。室内与现场试验证明,掺加纤维明显提高了封层的强度,减少裂缝,延长封层的使用寿命,效果良好。
2‰ polypropylene fiber were added to slurry mixture, which resulted in increase of moisture content of slurry and hasn＇t influence on initial setting time. Laboratory and field tests showed that the slurry mixture with polypropylene fiber improved effectively performances of seal courses, such as increasing strength, reducing crack and prolonging service life.
