中文摘要：
采用聚合物纤雏和木质素纤雏混合使用方式，通过马歇尔试验、车辙试验、冻融劈裂试验和抗反射裂缝性能试验进行混杂纤维增强沥青混合料的路用性能和抗反射裂缝性能的研究。结果表明：混杂纤雏能够显著提高沥青混凝土的高温抗车辙性能、低温抗裂性能和良好的抗裂缝反射能力，表现出较高的性价比。图2，表4，参8。
英文摘要：
A blend of polymer fiber and lignin fiber was used to improve the overall performance and decrease the project cost. Its pavement performance and resistance of reflective cracking were investigated by Marshall test, wheel track test, freezing-and-thawing cracking test and anti-reflective cracking test. Results indicate that hybrid fiber improves the high temperature anti-rutting and low temperature anti-cracking performance and good capacity of anti-reflective cracking, exhibiting sound cost-effectiveness. 2figs., 4tabs., 8refs.
