Distress Identification, Cost Analysis and Pavement Temperature Prediction for the Long-Term Pavement Performance for Western Australia

Pavement performance prediction model development for Tehran

Highways and in particular their pavements are the fundamental components of the road network. They require continuous maintenance since they deteriorate due to changing traffic and environmental conditions. Monitoring methods and efficient pavement management systems are needed for optimizing maintenance operations. Pavement performance prediction models are useful tools for determining the op...

Automated Pavement Distress Data Collection and Analysis:

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...

Calibration of Pavement ME Design and Mechanistic-Empirical Pavement Design Guide Performance Prediction Models for Iowa Pavement Systems

The AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) pavement performance models and the associated AASHTOWare® Pavement ME Design software are nationally calibrated using design inputs and distress data largely from the national Long-Term Pavement Performance (LTPP). Further calibration and validation studies are necessary for local highway agencies’ implementation by taking into acc...

Adaptive Imaging Techniques for Pavement Surface Distress Analysis

The Local Authority road networks commonly comprise roads of various functional characteristics and a variety of construction types. In this paper we investigate about the use of digital techniques to obtain field data to increase safety and reduce labour (cost) requirements using a semi-automated distress collection and measurement system. In particular, the proposed algorithm automatically de...
