This paper describes a 3-D automated pavement distress data collection and analysis system based on NRC’s Biris sensor technology. The paper introduces the problem to be solved, the selected design criteria, and the adopted solution to monitor the quality of road surfaces. The system geometry for the acquisition of the threedimensional coordinates of pavement surface distresses is presented. Mu...

Pavement condition assessment is an indispensable constituent in maintaining roadway infrastructure. Current practices for pavement condition assessment are labor intensive which introduce subjectivity in pavement rating and are time consuming. Automated methods rely on full 3D reconstruction of the pavement surface which introduces high equipment and computation costs. This paper presents a me...

15. Supplementary Notes Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. Project Title: Implementation of Automated Pavement Distress Rating Systems 16. Abstract This paper presents the image-processing algorithm customized for high-speed, real-time inspection of pavement cracking. In the algorithm, a pavement image is divided ...

Pavement condition assessment is essential when developing road network maintenance programs. In practice, the data collection process is to a large extent automated. However, pavement distress detection (cracks, potholes, etc.) is mostly performed manually, which is labor-intensive and time-consuming. Existing methods either rely on complete 3D surface reconstruction, which comes along with hi...

• Road-pavement surface monitoring, distresses classification and measurement. Comparison of crowdsensing-based monitoring technologies visual inspections. Efficiency effectiveness road-pavement surveys for optimal maintenance. Pavement-surface characteristics should be considered during road maintenance safe comfortable driving. A detailed up-to-date report network conditions is required to op...

In this paper, the potential use of an exponential hidden Markov model to model a hidden pavement deterioration process, i.e. one that is not directly measurable, is investigated. It is assumed that the evolution of the physical condition, which is the hidden process, and the evolution of the values of pavement distress indicators, can be adequately described using discrete condition states and...

Over the last decade, unexpected and sudden pavement failures have occurred in several provinces in South Korea. Some of these failures remain unexplained, further illustrating the gaps in our knowledge about binder chemistry. To prevent premature pavement distress and enhance road performance, it is imperative to provide an adequate characterization of asphalt. For this purpose, the current re...

The current project, funded by MIOH-UTC for the period 1/1/20094/30/2010, is concerned with the development of the framework for a transportation facility inspection system using advanced image processing techniques. The focus of this study is on the technical details of investigating and utilizing state-of-the-art image analysis techniques to further advance research in image processing based ...
