| 摘 要： | 混凝土桥面的沥青铺装层在外部荷载作用下的应力比较复杂,高温稳定性是铺装层材料的一项重要指标。通过车辙现场测量、钻芯取样的野外鉴定以及铺装层的车辙室内试验,研究桥面铺装层的SMA-13,AC-20改进型,SMA-10几种混合料高温稳定性。研究结果不仅给铺装层沥青混合料配合比设计提供有力依据,同时也给类似的工程实践提供一定的借鉴作用。

| Abstract: | Bituminous pavement on concrete bridge is of a complex property because applied loads give rise to stress response.The stability in high-temperature environment is an important parameter of pavement materials.To analyze the pavement materials,the stabilities of SMA-13,AC-20 improver,SMA-10 in high-temperature environment are examined by furrow survey,core sampling in the field and furrow test indoors.Such a study can not only offer a reliable basis for mixture design but it can also serve as references in similar engineering practice. |
