摘要
采用了德国JRS、国产某BH及新型絮状木质纤维,通过谢伦堡沥青析漏、马歇尔稳定度、动稳定度、水稳定性、渗水系数及构造深度等试验,研究木质纤维性能对提高沥青混凝土的路用性能的影响。结果表明,易于分散、低含水率、高吸油率、惰性大、动弹模高的木质纤维有利于增强SMA的路用性能。
In this paper JRS loose cellulose fibers made in Germany,BH loose cellulose fibers made in China and a new kind of cellulose fibers are used in SMA, presenting an analysis about such properties of cellulose fibers-en- hanced stone mastic asphalt as its Schellenberg binder drainage test, Marshall stability, high temperature performance, water stability and skid resistance. Through comparing the no-fiber stone mastic asphalt with the fiber stone mastic as- phalt, the mechanism of collulose fiber strengthening SMA is investigated. The experiment testifies that low water con- tent,high oil absorption,the big inertia and high move elastic modular ration of cellulose fibers are good for strengthe- ning the properties of SMA.
