Condition Survey for Evaluation of Pavement Condition Index of a Highway

Considering a New Sample Unit Definition for Pavement Condition Index

One of the main components of pavement management system (PMS) is pavement evaluation. Several indices have been defined for the evaluation of existing pavement. The Pavement Condition Index (PCI) is a common index used for pavement evaluation. In order to calculate PCI, a significant volume of condition data -based on distress surveying- is required. The objective of this research is to reduce...

Evaluation and Validation of a High-speed Multi- Function System for Automated Pavement Condition Survey

Manual surveys still represent the most widely used means for inspecting and evaluating pavements. Manual rating of pavements through windshield surveys to identify the types of surface cracking and other distresses leads to relatively slow evaluation. Furthermore, the survey crew must sometimes physically be in the travel lane to evaluate the pavement, exposing themselves to hazardous conditio...

Subsurface Condition Evaluation for Asphalt Pavement Preservation Treatments

Neural Networks in Stereo Vision Evaluation of Road Pavement Condition

This study presents the method for the measurement of road pavement condition based on a stereo vision method of surface representation. The road is represented as a set of points in 3D space. Problems of stereo vision analysis regarding the ambiguity of matching points images, discontinuity depth for neighboring objects registered on the images, etc. were redacted by used neural networks. The ...

Prediction of The Pavement Condition For Urban Roadway A Tehran Case Study (RESEARCH NOTE)

This report is the result of a research project on a pavement management system that was preformed by the Transportation Division of Iran University of Science and Technology. Information used in the project was collected from 20 zones of the Tehran Municipality. Any maintenance and repair system for roads is normally compared of a number of general and coordinated activities in conjunction wit...
