<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。

Bamboo-wood composites laminated veneer lumber (LVL) was treated under different temperature and humidity conditions. The mechanical properties of bamboo-wood composites LVL after the treatment were discussed. The results showed: (1) After the treatment of high temperature and humidity, all the mechanical properties of the LVL decreased obviously, in which, MOE decreased 30.70% in average, MOR decreased 38.3% in average, toughness decreased 11.7% in average. (2) After the treatment of low temperature, the MOE and MOR of bamboo-wood composites LVL revealed the trends of slight increase, the average increase rate of MOE was 2.5%, the average increase rate of MOR was 5.4%, the average decrease rate of toughness was 37.9%. (3) During the treatment of fluctuation from high temperature to low temperature, the MOE and MOR of bamboo-wood composites LVL were in the state of fluctuation, the increase rate or decrease rate of MOE was less than 5%, the increase rate or decrease rate of MOR was less than 10%, toughness displayed the trend of decrease, the decrease rate was 18.7% in average.
