摘要：
本发明涉及一种能改善沥青路面性能的添加剂，具体涉及一种能提高沥青路面抗裂和抗折性能的混杂纤维。本发明要解决现有技术存在的综合性能不高，成本高的问题，现采用的技术方案是：一种能提高沥青路面抗裂和抗折性能的混杂纤维，包括聚酯纤维：15％-35％，木质纤维：35％-55％，聚丙烯腈纤维：15％-35％，维纶纤维：15％-35％。与现有技术相比，本发明的优点是：效果好：采用本发明的技术可以较好地改善沥青胶浆的抗剪切及车辙性能，具有良好的抗变形能力；是实现既增强又增韧、节省工程造价、减轻混凝土自重的一条有效途径。
摘要（英）：

The invention relates to an additive capable of improving bituminous pavement property, in particular to an assorted fibre capable of improving crack resistance and fracture resistance of bituminous pavement. The invention aims to solve the problems of low combination property and high cost in the prior art. The adopted technical scheme is as follows: the assorted fibre capable of improving crackresistance and fracture resistance of bituminous pavement comprises 15-35% of polyester fibre, 35-55% of wood fiber, 15-35% of polyacrylonitrile fibre and 15-35% of vinylon fiber. Compared with the prior art, the invention has the advantage of favorable effect; and the technology of the invention can better improve the shear resistance and the anti-rutting property of asphalt mastic, has favorable non-deformability and provides an effective path for realizing the purposes of strengthening, toughening, saving construction cost and lightening concrete deadweight.
