Pavements are important assets to the safety and serviceability of road networks. Due to their fast deterioration and stringent municipal budgets, allocating the limited rehabilitation funds becomes a complex task. In this paper, an efficient heuristic approach for fund allocation has been introduced. After prioritizing pavements based on different criteria, such as AADT, pavement IRI, and road...

Infrastructure systems in the US are in an urgent need of maintenance and rehabilitation. According to the most recent factsheet published by the American Society of Civil Engineers, one of the top five infrastructure concerns of today in the US is transportation systems. The major challenge facing maintenance managers in state Departments of Transportation (DOTs) today is to preserve the road ...

Life-Cycle Assessment (LCA) analyzes the total energy and resource requirements and environmental impact of human-designed systems. Both policymakers and industry have shown a great deal of interest in applying LCA as a decision-making criterion during planning and design for new pavement construction, and maintenance and rehabilitation activities. This interest results from two different persp...

As one type of pavement distresses, potholes are important clues indicating structural defects of the asphalt road, and accurately detecting these potholes is one of important tasks for determining proper strategies of asphalt-surfaced pavement maintenance and rehabilitation. However, manually detecting and evaluating methods are expensive and timeconsuming. Thus, several efforts have been made...

The development of a knowledged-based expert system to assist ~he New Mex~co State Highway and Transportation Department m the evaluation and design of rehabilitation schemes for flexible pavements is described. The system uses information provided by users to establish preliminary rehabilitation schemes that would be reasonable and cost-effective. A cost-estimate module for ~anking th~ rehabil...

Pavement deflection data are often used to evaluate a pavement’s structural condition non-destructively. It is essential not only to evaluate the structural integrity of an existing pavement but also to have accurate information on pavement surface condition in order to establish a reasonable pavement rehabilitation design system. Pavement layers are characterized by their elastic moduli estima...

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...

This study demonstrates the use of Class F fly ash in combination with lime or lime kiln dust in the full depth reclamation (FDR) of asphalt pavements. FDR, in the context of this paper, is a process of pulverizing a predetermined amount of flexible pavement that is structurally deficient, blending it with chemical additives and water, and compacting it in place to construct a new stabilized ba...

The surface layer of road pavement has a particular importance in relation to the satisfaction of the primary demands of locomotion, such as security and eco-compatibility. In order to reduce road maintenance and rehabilitation costs and optimize the service condition of road networks, pavement management systems (PMS) need reliable and detailed data on the status of the highway network.
