This work proposes an experimental-based model for the assessment of the stiffness of a road flexible pavement using ground-penetrating radar (GPR – 2 GHz horn antenna) and light falling weight deflectometer (LFWD) non-destructive testing (NDT) methods. It is known that the identification of early decay and loss of bearing capacity is a major challenge for effective maintenance of roads and the implementation of pavement management systems (PMSs). To this effect, a time-efficient methodology based on quantitative and qualitative modelling of road stiffness is developed. The viability of using a GPR system in combination with LFWD equipment is also proven.

这项工作提出了一个基于实验的模型，用于使用探地雷达（GPR – 2 GHz喇叭天线）和轻型重量偏转仪（LFWD）无损测试（NDT）方法评估道路柔性路面的刚度。众所周知，对于有效维护道路和实施路面管理系统（PMS）而言，识别早期衰减和承载力损失是一项重大挑战。为此，人们开发了一种基于定量和定性道路刚度建模的省时方法。还证明了将GPR系统与LFWD设备结合使用的可行性。
