Characterization of asphalt pavements, based on ground spectroradiometers, has been studied in the past to determine their spectral response concerning the physical, chemical, and condition properties of the pavement. This paper suggests an alternative technique for characterizing ageing of asphalt pavements using a colorimeter. Colorimeters are considered as affordable equipment in laboratories in contrast to other scientific instruments and turn remote sensing ground techniques more accessible to industry. Therefore, the study proposes a new methodology indicating how colorimeters can be used in combination with satellite data for the age characterization of asphalt pavements. Spectroradiometer data are compared in a two-way methodology to colorimeter data. The final steps of the methodology used in the study show very similar results for both equipment after a comparison of separability indices (Euclidean and Mahalanobis distances). It is a fact that colorimeter data can be used as ground truth data. The application was performed using an in-band analysis of WorldView 3 (WV3) spectral bands situated in the visible electromagnetic spectrum. Based on the findings of this study, we proposed the Normalized Difference Equation/filter for asphalt Pavement Age characterization Index (NDPAI).

使用色度计支持沥青路面的遥感技术

过去已经研究了基于地面光谱仪的沥青路面特性，以确定其与路面的物理，化学和状态特性有关的光谱响应。本文提出了一种使用色度计表征沥青路面老化的替代技术。与其他科学仪器相比，色度计被认为是实验室中可负担的设备，并使遥感地面技术更易于工业使用。因此，这项研究提出了一种新的方法，该方法表明如何将色度计与卫星数据结合使用来表征沥青路面的年龄。分光光度计数据通过两种方法与色度计数据进行比较。比较可分离性指标（欧几里得距离和马氏距离）后，研究中使用的方法的最后步骤对两种设备显示出非常相似的结果。比色计数据可以用作地面真实数据是事实。该应用程序是通过对位于可见电磁光谱中的WorldView 3（WV3）光谱带进行带内分析来执行的。基于这项研究的结果，我们提出了沥青路面年龄特征指数（NDPAI）的归一化差分方程/滤波器。
