福塔纤维(FORTAR○AR)是一种新型的聚合物有机纤维,它由聚丙烯(Po lypropy lene)和芳纶(K ev lar)按照质量比3∶1混合而成。对掺加0.045%福塔纤维、0.3%的德兰尼特纤维(D o lan it)以及不加纤维的沥青混合料的高温稳定性、低温抗裂性以及水稳定性等路用性能进行了评价,结果表明福塔纤维沥青混合料具有优良的路用性能;继而对福塔纤维改善沥青混合料路用性能的机理进行了分析。
FORTAR® AR is a new type of polymeric organic fiber made from polypropylene and Kevlar in a mass ratio of 3: 1. The road performance such as high temperature stability, low temperature crack resistance and water stability of 0.045% Feta fiber, 0.3% D o lan it and asphalt without fiber were tested The results show that Fota fiber asphalt mixture has excellent road performance; and then the mechanism of Feta fiber improving road performance of asphalt mixture is analyzed.
