Radar database over narrow debonded areas into pavement structure

This database was collected over narrow artificial disbonded areas during an accelerated pavement testing at univ. Gustave Eiffel's carousel. GPR data have been collected over tenartificial defects (tack-free, geotextile and sand-based), which were embedded between the top and the base layers. The data collection was organized in a two-stage experiments and covers the full life-cycle of the pavement structure. During the first stage that took place in 2012-13, data were collected at different stages from 0k to 300k loading cycles. The second measurement campaign was performed in 2019-2020 and lasted up to 800k loading cycles. This database completes a first one dedicated to three largest defects, and presented in " Radar database over large debonded areas into pavement structures

本数据库是在古斯塔夫·埃菲尔大学转盘式加速路面试验装置上开展加速路面试验期间，针对狭窄人工脱粘区域采集所得。研究团队在埋置于路面面层与基层之间的10个人工缺陷（涵盖无粘层、土工织物及砂基三类缺陷）上方采集了探地雷达（Ground Penetrating Radar，GPR）数据。本次数据采集分为两阶段实验，完整覆盖了路面结构的全生命周期：第一阶段实施于2012-2013年，在0至30万次加载循环的不同阶段完成数据采集；第二阶段测试于2019-2020年开展，累计加载循环次数达80万次。本数据库补充了此前针对三大缺陷的首个同类数据库，该数据库曾发表于"Radar database over large debonded areas into pavement structures"。

背景概述

该数据集包含在加速路面测试期间收集的狭窄人工脱粘区域的雷达数据，覆盖了从0k到800k加载周期的全生命周期数据。数据集特别关注三种人工缺陷（无粘性、土工布和基于沙子的缺陷），并分为2012-13年和2019-20年两个阶段的实验数据。
