An analytic hierarchy process and Markov chain based approach for condition rating and dynamic service life prediction of retaining walls
… and Markov Chain to rate and predict the future condition of retaining walls respectively. Based on the Field Survey of candidate retaining walls, the research uses AHP for hierarchical configuration and pair-wise comparison of retaining wall elements (and sub-elements) – to generate relative …

Implementation of the DER rating system within a power generation environment
… of defect, Extent and Relevancy of defect) rating system, used for road network infrastructures, to the support structures of a dry cooling tower in a power generation environment. The DER is a defect-based rating system developed locally by the Built Environment Division of the Council for …

Application of Markov process to pavement management systems at the network level
… process. The system uses PCI method for pavement condition rating. The pavement performance prediction model has been developed based on the Markov process. Homogeneous and non-homogeneous Markov chains have been used in the model development. The comparison of the results from the Markov …

Effects of disparate information levels on bridge management and safety
… are made come from visual inspection based condition ratings. These visual inspections are used to evaluate the extent of deterioration present and assign a condition rating based on a predefined scale of damage, after which bridge managers trigger further assessment or intervention actions …

Framework for Rating Roadway Assets at the Corridor Level
… states have employed their own methodology for rating each asset type. This makes comparison of assets between states difficult. Several methods in use have provided a way to effectively rate an asset, but no method exists that can be used to compare ratings in different states. To successfully …

Visual inspection and bridge management
… method for bridge structures, whereby a condition rating is assigned reflecting the structural condition of a bridge, based on the judgements of a trained inspector. The impact of data collected from visual inspection is contingent on its ability to guide towards optimal maintenance …

Investigation on the mechanisms of block cracking in asphalt pavements
… covered in many pavement evaluation guides and condition rating systems, the underlying mechanisms of block cracking have not been fully investigated. Therefore, understanding the mechanisms behind block cracking and tailoring preventive solutions merits rigorous investigation. In this thesis, a …

Correlation of corrosion measurements and bridge conditions with NBIS deck rating
… and NBIS. Instead, the inspection and bridge rating guidelines of federally mandated programs such as NBIS are so vague as to allow for a relatively subjective application by the field inspectors. Clear cover depths, resistance, corrosion potentials, linear polarization data, as well as …

Macroinvertebrate Biomonitoring Criteria and Community Composition in Seasonal Floodplain Wetlands of the Upper Missouri River
… scores indicated similarity to the reference condition), summed and standardized for a final M-IBI that ranged from 0 to 100. The M-IBI was found to be robust to inter-year variation, but displayed considerable intra-year variation implying that time of year wetlands are sampled is critical …

Laboratory characterization and field performance of hot in-place recycled mixtures
… The timing of treatment and the existing condition of the pavement are the deciding factors for the efficiency of HIR. The objective of this study is to characterize material properties and field performance of HIR treatments. Three field sites were evaluated as part of the study: …

Artificial Intelligence Driven Infrastructure Management and Maintenance Plan
… these increasing loads and harsh environmental conditions that Florida is subject to requires an enhanced infrastructure management program. Additionally, there is a need to eliminate inconsistencies in permit applications and derive a uniform maintenance practice for Florida’s infrastructure. …

Improvement of the approaches to monitoring of reinforced concrete bridges subjected to chloride-induced reinforcement corrosion in bridge management systems
… reinforcing in concrete corrode when certain conditions (e.g., carbonation, chlorides, insufficient cover and moisture) are met. Even though RC bridges are built to provide a service over a specified period, their serviceability changes over time due to gradual deterioration. In the marine …

Development of a pile condition index and a road map for the development of a structural section rating
… of waterfront facilities, routine infrastructure condition assessments are a necessity. Damage resulting from overloading events and deterioration caused by any number of mechanisms can significantly comprise the physical integrity and operational condition of a facility. Existing methods for …
