The invention discloses an asphalt mortar multi-stress creep testing method based on different driving behavior combinations of a road intersection. The method comprises the following steps of: 1, acquiring traffic information, including the vehicle speed, vehicle head distance and traffic volume of passing vehicles, of a road intersection to be tested; 2, determining the category, the weight andthe loading mode of the driving behavior; 3, calculating the loading period lengths of different driving behaviors in the test; and 4, carrying out a multi-stress creep test on the asphalt mortar. According to the method disclosed by the invention, the stress characteristics of the asphalt mortar in an actual road intersection are fully considered; the vehicle speed and the vehicle head distance data of the actual road intersection are utilized; the indoor loading modes corresponding to different driving behaviors are deduced, the high-temperature creep characteristics of the asphalt mortar under the multiple stress creep test can be accurately simulated through combination of the different driving behaviors, and the test method is simple, easy to implement, reasonable in test condition control and stable and reliable in test result.

    本发明公开了一种基于道路交叉口不同驾驶行为组合的沥青砂浆多重应力蠕变测试方法,包括以下步骤:步骤一:获取待测道路交叉口交通信息,包括通过车辆的车速、车头间距和交通量;步骤二:确定驾驶行为的类别、权重和加载模式;步骤三:计算试验中不同驾驶行为的加载周期长度;步骤四:进行沥青砂浆的多重应力蠕变试验。本发明方法充分考虑了沥青砂浆在实际道路交叉口当中的受力特点,利用实际道路交叉口的车速和车头间距数据,推导不同驾驶行为对应的室内加载模式,通过不同驾驶行为的组合可以准确地模拟沥青砂浆在多重应力蠕变试验下的高温蠕变特性,本发明试验方法简单易行,试验条件控制合理,试验结果稳定可靠。
