已服役25年济青高速公路沥青层切割试件加速加载车辙试验数据

"已服役25年济青高速公路沥青层切割试件加速加载车辙试验数据"为已服役25年济青高速公路沥青层切割试件，经ALT-S100缩尺加速加载试验机在试验温度60℃、三种不同加载速度3.5km/h、4.5km/h和5.5km/h条件下，得到的沥青层断面车辙数据，既包含了不同加载次数时的最大车辙深度，也包含了不同加载次数时的断面轮廓数据。采用的加载设备为ALT-S100，可准确控制车速、轮载、胎压和温度；采用的路面车辙检测设备为激光断面车辙仪，分辨率0.05mm。加载的试件来自济青高速公路旧沥青路面整个沥青层，试件高度约220mm，共加载了11.5万次缩尺加速加载，相当于149.9万次当量轴载作用次数。数据量为55KB。

Accelerated Loading Rutting Test Dataset of Core Specimens Cut from the 25-Year-Serviced Jinan-Qingdao Expressway Asphalt Layer. This dataset is derived from accelerated loading rutting tests conducted on core specimens cut from the full asphalt layer of the aged Jinan-Qingdao Expressway that has been in service for 25 years. The core specimens have an approximate height of 220 mm. The tests were performed using an ALT-S100 scaled accelerated loading testing machine, under a fixed test temperature of 60℃, with three different loading speeds: 3.5 km/h, 4.5 km/h, and 5.5 km/h. A total of 115,000 scaled accelerated loading cycles were applied, which is equivalent to 1,499,000 equivalent axle load cycles. The ALT-S100 equipment can accurately control the loading speed, wheel load, tire pressure and test temperature. The rutting cross-sections were detected using a laser cross-sectional rutting meter with a resolution of 0.05 mm. The dataset contains two categories of data: the maximum rutting depth at different loading cycles, and the cross-sectional profile data corresponding to each loading stage. The total file size of this dataset is 55 KB.
