In recent years, there has been renewed interest in developing Moving Measurement Platforms (MMPs) to replace the Falling Weight Deflectometer (FWD) which currently serves as the industry standard for project-level pavement evaluation. The purpose of this study was to contribute to the transition efforts from FWD to MMPs. While focusing on a new MMP device (called Raptor) based on line profile sensing technology, the work addressed three fundamental aspects needed for eventual field data assessment and industry acceptance: (i) Loading and measurement setup – presenting an innovative device consisting of a beam equipped with several line profilers and also motion tracking sensors. By means of image analysis, this configuration allows for tracking a point on the pavement surface and measuring displacement information while moving. (ii) Interpretation method – capable of accepting device-measured data as input, and providing elastic properties for a layered pavement model. (iii) Sensitivity to measurement errors – where the interpretation method is first validated and then interrogated for error effects on the inferred moduli. Overall, the obtained results provide basic confidence in the device and the interpretation method, and demonstrate that the technology has the potential to meet project-level pavement evaluation needs.

近年来，人们对开发移动测量平台 (MMP) 以取代落锤式挠度计 (FWD) 重新产生兴趣，后者目前作为项目级路面评估的行业标准。本研究的目的是促进从 FWD 到 MMP 的过渡工作。在专注于基于线轮廓传感技术的新型 MMP 设备（称为 Raptor）的同时，该工作解决了最终现场数据评估和行业接受所需的三个基本方面：(i) 加载和测量设置——展示一种由光束组成的创新设备配备了多个线轮廓仪和运动跟踪传感器。通过图像分析，这种配置允许跟踪路面上的一个点并在移动时测量位移信息。(ii) 解释方法——能够接受设备测量数据作为输入，并为分层路面模型提供弹性特性。(iii) 对测量误差的敏感性——首先验证解释方法，然后询问对推断模量的误差影响。总体而言，获得的结果为该设备和解释方法提供了基本的信心，并证明该技术具有满足项目级路面评估需求的潜力。
