博尼维(Bonififbers)是美国Kapeio公司研究开发生产的一种聚酯类纤维材料,掺入沥青混合料后由于其良好的粘接、加筋性能,有效提高了沥青路面的柔韧性、高温抗车辙能力、低温抗裂性、抗疲劳性能以及抗水损害性能等路用性能,从而延长了路面的使用寿命。笔者在云南宣(威)倘(塘)二级公路沥青路面铺筑时,在曲线半径小、纵坡大的重交通量路段探索应用了博尼维聚酯纤维沥青混合料,经过几年的实践证明,其使用效能良好,具有很好的推广价值。
Bonififbers is a kind of polyester fiber material researched and developed by American Kapeio Company. Due to its good bonding and reinforcing properties after being added into asphalt mixture, Bonififbers can effectively improve the flexibility of asphalt pavement. High temperature resistance Rutting ability, low temperature crack resistance, fatigue resistance and water damage resistance and other road performance, thereby extending the service life of the road. In Yunnan Xuan (Granville) If (Tong) Class II asphalt pavement construction, the curve of small radius, longitudinal slope of the heavy traffic explored the application of Boniface polyester asphalt mixture, after several years Practice has proved that its use of good performance, with good promotional value.
