ABSTRACT: Most pavement maintenance management systems tend to be either non-analytical databases or statistical correlation models. However, pavement maintenance is part of a complex system (comprising the road pavement, the environment, diverse users, the maintenance authority and Local/State/Federal Governments) that has significant feedbacks, making it a suitable field for system dynamics e...

The Minnesota Department of Transportation (Mn/DOT) Office of Materials and Road Research advances the state of the practice of pavement design, construction, and maintenance by conducting and participating in pavement and materials research projects, implementation of research results, and supporting practitioners. One of the many research strategies is the study of tire-pavement noise using M...

The accumulated irreversible deformation in pavement under repeated vehicle loadings will cause fatigue failure of asphalt concrete. It is necessary to monitor the mechanical response of pavement under load by using sensors. Previous studies have limitations in modulus accommodation between the sensor and asphalt pavement, and it is difficult to achieve the distributed monitoring goal. To solve...

This brief provides findings on the observed effect of initial pavement smoothness (also known as initial roughness, or as-constructed roughness) on the long-term pavement roughness progression of asphalt overlays. The relationship can be used as a measure for estimating the long-term effect of pavement smoothness and for consideration when developing smoothness specifications and/or payment ad...

Asphalt pavement distress, the various defects such as holes and cracks, represent a significant engineering and economic concern. It is estimated that pavement defects cause damage costing $10 billion each year in the United States alone [10]. One important step in managing this problem is accurately assessing the pavement condition and its change over time. In this paper we compare three meth...

This report is the result of a research project on a pavement management system that was preformed by the Transportation Division of Iran University of Science and Technology. Information used in the project was collected from 20 zones of the Tehran Municipality. Any maintenance and repair system for roads is normally compared of a number of general and coordinated activities in conjunction wit...

Weak bonding between layers of pavement leads to damages on the composite pavement. Bonding plays an important role in the durability and maintenance of composite pavement layers. The present study evaluates the factors effective in bond strength of the interface between concrete and asphalt pavements. The factors considered for this purpose include steel slag percentage in the concrete pavemen...

The present paper deals with a view of the availability of high-speed sensor profilers, which has given dramatically increased possibilities to analyze imperfections in pavement surfaces such as roughness. Technical parameters of such profilers, for sensing and analyzing pavement surface profile are described. In addition, the main investigation concentrates on the evolutional process of paveme...

Concrete block pavement (CBP) is a durable pavement for carrying light as well as heavy loads, and it is being used widely for construction of city streets, parking places, gas stations, container stacking yards, residential areas and low volume roads. This paper presents the findings of a laboratory investigation on structural behaviour of CBP. Plate load and Accelerated Pavement tests were ca...

The depiction of the irregularity in nature is crucial for the realistic representation of the real world. For example, real pavement blocks are not always paved evenly, but partially sink over time. Many games or virtual reality systems however represent the pavement too neatly with perfectly flattened surface and clean texture images. In this paper, we suggest a method for representing realis...
