Subsurface Condition Evaluation for Asphalt Pavement Preservation Treatments

Spectrometry and Hyperspectral Remote Sensing for Road Centerline Extraction and Evaluation of Pavement Condition

Remote sensing may offer quick and economical methods of surveying road centerline geometry and condition. This research uses a combination of 4 m, 224-band AVIRIS hyperspectral imagery, and about 6000 field-gathered spectra, to develop a spectral library of urban materials. It attempts to extract roads of various types, and investigates the spectral signatures associated with different qualiti...

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...

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 ...
