The bearing capacity and service life of a pavement are adversely affected by the presence of undrained water in the pavement layers. In cold winter climates, such as in Iowa, this problem is magnified further by the risk of frost damage when water is present. Therefore, wellperforming subsurface drainage systems form an important aspect of pavement design by the Iowa Department of Transportati...

A pavement management system (PMS) is a valuable tool and one of the critical elements of the highway transportation infrastructure. Since a vast amount of pavement data is frequently and continuously being collected, updated, and exchanged due to rapidly deteriorating road conditions, increased traffic loads, and shrinking funds, resulting in the rapid accumulation of a large pavement database...

This paper describes the Accelerated Testing with the LINTRACK-facility of the innovative ‘Rollpave’ test pavement that was developed within the theme ‘Modular Pavement Structures’ of the project ‘Roads for the Future’ of the Dutch Ministry of Transport, Public Works and Water Management. The concept of ‘Rollpave’ is a thin pre-manufactured asphalt wearing course that is rolled on a reel. On si...

An accurate and regular survey of the road surface distresses is a key factor for pavement rehabilitation design and management, allowing public managers to maximize the value of the continuously limited budgets for road improvements and maintenance. Manual pavement distress surveys are labor-intensive, expensive and unsafe for highly-trafficked highways. Over the years, automated surveys using...

Government agencies and consulting companies in charge of pavement management face the challenge of maintaining pavements in serviceable conditions throughout their life from the functional and structural standpoints. For this, the assessment and prediction of the pavement conditions are crucial. This study proposes a neuro-fuzzy model to predict the performance of flexible pavements using the ...

The southwest Kansas region is one of the centers in the United States for the production of processed beef and related industries. Trucks utilized to support these industries cause noteworthy damages to the regional highway pavements. The objective of this research project was to determine the pavement damage cost of a typical highway section in southwest Kansas attributed to the truck traffic...

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...

Pavement friction is an important topic addressed by transportation agencies to reduce the number of traffic crashes and fatalities caused poor between tires pavement surface. management (PFM) provides essential tools techniques effectively evaluate conditions provide informed maintenance decisions using surface treatments. State Departments Transportation (DOTs) utilize various engineering pra...

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...

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...
