<正>介绍了聚醋玻纤布的力学特性和功能，以复合沥青混合料室内试验来比较该材料与纯沥青混合料在各种力学性能上的差异，并应用于沪宁高速公路的扩建工程中。结果表明：聚醋玻纤布可以提高沥青路面的使用性能，改善新老路面接缝处的应力集中现象，减缓反射裂缝的产生，从而达到增加路面使用年限的目的。

The mechanical character and the function of fiberglass/ polyester paving mat was introduced, the mechanical property of the paving mat was compared with the pure bitumen compound based on the indoor test of composite asphalt mixture. The practical application of fiberglass/ polyester paving mat in the Hu-Ning highway extension project was introduced. The result shown that it can improve the capability of the bitumen pavement, minimize the stress concentration in the joint between the old and new surfaces, mitigate and postpone the reflection crack of asphalt pavement road, prolonging the service life of the pavement.
