It is well known that road safety issues are closely dependent on both pavement structural damages and surface unevenness, whose occurrence is often related to ineffective pavement asset management. The evaluation of road pavement operability is traditionally carried out through distress identification manuals on the basis of standardized comprehensive indexes, as a result of visual inspections...

Due to traffic loading and weathering, highway pavements deteriorate starting immediately after construction. Many rehabilitation methods are available to bring deteriorated pavements back to an appropriate level of service for road users. One of these methods, chip seal, has been widely used in many states, including Kansas. This study evaluated the performance of chip seal treatments in Kansa...

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...

Rough Set Theory (RST) is an induction based decision-making technique, which can extract useful information from attribute-value (decision) table. This study introduces RST into pavement management system (PMS) for maintenance and rehabilitation (M&R) strategy induction. An empirical study is conducted by using the pavement distress data collected from 7 county roads by experienced pavement en...

The objective of this project was to develop a structural index for use in network-level pavement evaluation to facilitate the inclusion of the pavement’s structural condition in pavement management applications. The primary goal of network-level pavement management is to provide the best service to the users for the available, often limited, resources. Pavement condition can be described in te...

Road pavement maintenance today relies mainly on manual pavement condition inspection and distress rating; however, this manual method is costly, labour-intensive, time-consuming, and dangerous to inspectors and may affect traffic flows. Moreover, such method is very subjective and may have a high degree of variability, being unable to provide meaningful information. Additionally, since using t...
