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...
متن کاملLong Term Pavement Performance Program Protocol for Calibrating Traffic Data Collection Equipment
The LTPP program acknowledges that weigh-in-motion (WIM) and automatic vehicle classification (AVC) are not mature technologies. As such, participating agency and site-specific conditions may legitimately warrant the use of procedures other than those presented below. In addition, LTPP recognizes that participating agencies use a variety of types of traffic data collection equipment and have di...
متن کاملTechnology Overview on Validating 3D Transverse Profile Data and Measurement of Pavement Surface Distresses
With the advancement of 3D line laser imaging technology (“3D technology”, hereafter for the sake of brevity), high-resolution 3D transverse profile data (“3D data”, hereafter for the sake of brevity), has gained widespread interest from researchers, industry and highway agencies and has been used for collecting pavement surface distresses. However, the study of data characteristics, e.g. data ...
متن کاملEstimation of Reshaped Profile of Berm Breakwaters Using Experimental Data
A reshaping berm breakwater is a type of rubble mound breakwater in which, its seaward slope is allowed to reshape under wave attacks. There are some key parameters in the reshaped seaward profiles, which can schematize the reshaped profile of a berm breakwater. A total of 412 test results was used directly to cover the impact of sea state conditions and structural parameters on these reshaping...
متن کاملDevelopment of An Artificial Neural Network Model for Asphalt Pavement Deterioration Using LTPP Data
Deterioration models are important and essential part of any Pavement Management System (PMS). These models are used to predict future pavement situation based on existence condition, parameters causing deterioration and implications of various maintenance and rehabilitation policies on pavement. The majority of these models are based on roughness which is one of the most important indices in p...
