摘要
对AC-13、OGFC-13、SMA-13三种类型的沥青混合料路用性能作了比较。又通过国内部分大桥的桥面采用SMA类沥青铺装层组合方案进行了调查。最后进行了试验,确定了上海市南北高架道路沥青面层改造方案采用温拌改性沥青混合料SMA,并确定了铺装结构厚度为3.5cm。
The author has drawn a comparison between 3 kinds of asphalt mixtures (AC-13, OGFC-13 and SMA-13) on their service performance and has made a careful investigation of SMA type pavement combination plans of partial bridge decks in China. Finally, Shanghai North & South Viaduct asphalt mat reconstruction plan has adopted warm-mix modified asphalt SMA with 3.5 cm thickness of paving structure.
