This report discusses the implementation of a pavement condition rating (PCR) procedure to sample sections of the road network system. The resources needed are identified for such implementation. The uses of PCR data at the network and project level are also identified. The report stresses the development of a data base for integration of the various engineering systems for pavement management ...

This study integrates ground spectrometry, imaging spectrometry, and in-situ pavement condition surveys for asphalt road assessment. There is strong spectral evidence for asphalt aging and deterioration processes, hence field spectra showed that asphalt aging and deterioration produce measurable changes in spectra as these surfaces undergo a transition from hydrocarbon dominated new roads to mi...

Pavement distresses (damages) are important information for evaluating the road condition and conducting the necessary road maintenance activities. Conventional human visual pavement distress detection method is time consuming, very expensive, labour-intensive and dangerous due to exposure to traffic. Numbers of methods have been introduced for road damage detection in the context of fine struc...

The purpose of this study is to build the binary logit model of an airport pavement that could monitor the pavement condition in near real time using microwave remote sensing satellite, then the relationship between the international roughness index (IRI) of an airport and backscattering values from PALSAR images of the ALOS satellite was determined. Total 390 data were used in analysis. This m...

In determining certain infrastructure rehabilitation needs, it is sometimes important to consider user perceptions along with physical measures of infrastructure condition. Pavement roughness is one such case. A critical determinant of public satisfaction, user perception of pavement roughness can potentially play a critical role in the allocation of resources to competing highway resurfacing p...

Road networks are a national critical infrastructure. The road assets need to be monitored and maintained efficiently as their conditions deteriorate over time. The condition of one of such assets, road pavement, plays a major role in the road network maintenance programmes. Pavement conditions depend upon many factors such as pavement types, traffic and environmental conditions. This paper pre...

The load-bearing capacity of pavement structures is a fundamental structural performance metric of transportation infrastructure networks in the context of safe and efficient movement of people and goods from one place to another. Non-destructive test (NDT) methods are typically employed to routinely evaluate the structural condition of pavement structures, their lifespan and the appropriate ma...

A potential automated pavement evaluation system to address multisensor applications; integrate different types of sensors , techniques, and information; and offer more sophisticated and intelligent processing capabilities for improved pavement management is described. The separate components of this system either now exist in prototype form or are under development . Such a system could automa...
