摘要
木质素纤维是SMA混合料中应用最为广泛的稳定剂,通过室内析漏试验、混合料路用性能试验及试验段实施,评价了絮状、颗粒状木质素纤维对SMA沥青混合料稳定性及施工和易性的影响。试验及工程实践表明,在最佳掺量条件下,两种纤维均可使SMA混合料达到稳定状态,混合料性能指标相当,但颗粒状纤维掺量对混合料稳定性及施工和易性的影响更为敏感。
Lignin fiber is the most widely used in SMA mixture of stabilizer,through Schellenberg Binder Drainage test,performance test and the test section,can evaluate the flocculent,granular lignin fiber stability of SMA asphalt mixture and the influence of construction workability. Test and engineering practice show that the optimal conditions,the dosage of two kinds of fiber can make the SMA mixture reach the stable state,the mixture performance indicators,but granular fiber content stability of mixture and the influence of construction workability more sensitive.
