Laboratory testing equipment for asphalt mixtures with three different functionalities is introduced. The rotary compactor and wheel tracker (RCWT) not only achieves realistic contact areas of actual pneumatic tyres but can also compact heavy-duty laboratory asphalt mixtures to the desirable density and conduct simulated wheel tracking tests (WTTs). The RCWT is able to replicate stone mastic asphalt full-scale site rollers. The simulated WTT, with actual pneumatic tyres, reproduced the non-uniform contact stresses as well as other non-linear and viscoelastic behaviours of the tyre–pavement interaction. Furthermore, the instrumentation system with fully calibrated sensors and data acquisition set-up captured all the crucial factors – including the temperature inside the asphalt mixture mat, vertical load, rutting depth and vertical compressive strain at the bottom of the asphalt layer – effectively and continuously.

用于车轮跟踪试验的重型沥青板的仪器

介绍了三种不同功能的沥青混合料实验室检测设备。旋转压路机和车轮跟踪器 (RCWT) 不仅可以实现实际充气轮胎的真实接触面积，还可以将重型实验室沥青混合料压实到所需的密度，并进行模拟车轮跟踪测试 (WTT)。RCWT 能够复制石膏沥青全尺寸工地压路机。使用实际充气轮胎的模拟 WTT 再现了非均匀接触应力以及轮胎与路面相互作用的其他非线性和粘弹性行为。此外，带有完全校准传感器和数据采集装置的仪表系统捕获了所有关键因素——包括沥青混合料垫内部的温度、垂直载荷、
