美国 SUPERPAVE的出现受到世界沥青工业界的重视。在热拌沥青铺路技术应用方面 ,对性能级沥青胶结料在HMA期间能够保证其产生的污染物挥发程度达到最低限值的施工温度条件也有了一定要求。由美国沥青协会、美国沥青铺路协会及州立沥青铺路协会共同组成的 APEC组织提出了性能分
The emergence of the United States SUPERPAVE by the world’s asphalt industry attention. In the application of hot asphalt paving technology, there are certain requirements on the construction temperature conditions that the performance grade asphalt cement can guarantee the volatilization degree of pollutants produced during the HMA to reach the minimum value. The APEC organization, composed of the American Asphalt Association, the American Asphalt Pavement Association and the State Asphalt Paving Association, proposes a performance score
