沥青混合料的性能矛盾及解决途径

The confliction performance and solutions for asphalt mixtures

回顾我国公路沥青路面的发展史可以看出,沥青路面的发展和变革,实际上是路面材料变革的历史。如今我国公路建设进入一个前所未有的大发展阶段,随着交通量的增大和轴载的增重,对沥青路面提出了更高要求。为此,我国公路部门开始了改性沥青和沥青玛蹄脂碎石混合料(SMA)的研究和应用。

In the history of asphalt pavement in China, its growthand evolution has been mainly the history of pavementmaterials. Now China has entered into a phase ofunprecedented growth in road construction, increasinghigh requirements are imposed on asphalt pavementalong with the increase traffic volumes and axle loads.Hence, the Chinese road department started theresearch and application of modified asphalt and SMA.
