摘要
通过对掺加沙生灌木纤维沥青混合料进行研究,确定出沙生灌木纤维最佳掺量和最佳沥青用量,并系统分析了沙生灌木纤维增强沥青混合料的高温稳定性、低温抗裂性、水稳定性及耐疲劳性。研究结果表明,在沥青混合料中掺入沙生灌木纤维,可以显著提高沥青混合料高温抗车辙性和抵抗裂缝的能力,从而使沥青混合料具有良好的抗剪强度和抗拉强度;同时,由于沙生灌木纤维的掺入,使沥青混合料具有较强的抗水损坏能力与耐疲劳性能,从而延长了沥青路面的使用寿命。
The best dosage of desert shrubs fiber and optimum asphalt content were identified through the research on desert shrub fiber in asphalt mixture, and systematically analyzed the capabilities of high temperature stability, low tempera- ture crack resistance,water stability and fatigue resistance. The results showed that the desert shrubs fiber in asphalt mix- ture can significantly improve the high temperature anti-rutting and the ability to resist cracking of the asphalt mixture, so that the asphalt mixture has good shear strength and tensile strength, at the same time, owing to the desert shrubs fiber in the asphalt mixture,the asphalt mixture also has a strong ability of anti-water damage and fatigue resistance,thus extending the life of the asphalt pavement.
