Current pavement design guides for Jointed Plain Concrete Pavements define one critical location at the mid-slab edge and assume that damage accumulates linearly and can be described via S-N curves. More recently, experiments have shown that damage does not accumulate linearly and a pronounced stress range effect exists. These two...
Evaluation of the Linear Damage Assumption in JPCP Bottom-up Fatigue Cracking
Effect of Nonuniform Foundation Support on Concrete Slab Responses
The ability to spatially map the stiffness of the foundation layers under concrete pavements with intelligent compaction has created a need to define limits on the allowable stiffness variations in a given construction area as well as the maximum size of a non-complaint area which does not require remedial action....
Technical and Economical Feasibility of Pavement Widenings in Cement Concrete in the Netherlands
In 2009 the Dutch Parliament amended special laws to speed up road widening projects. This situation opened possibilities for sustainable concrete pavements needing less maintenance, especially for the right-hand lane that takes the heavy traffic. This paper presents the results of a study carried out in 2009, by a working...
Decision Support Model for Road Pavements Based on Whole Life Costing, Life Cycle Analysis and Multi-Criteria Analysis
In response to the growing importance of sustainable building, designers, consultants and pavement managers now tend to make more rational decisions than before when comparing the pros and cons of the construction, maintenance and management of various types of road pavements. Asphalt and concrete pavements offer specific advantages that need...
Design Methods for Cement Bound Bases in Pavement Structures
Application of bound foundation materials is attractive and allows to reduce the required asphalt thickness due to the high stiffness of the cement bound material. Unfortunately, the design of a pavement with a bound base is not standard. This hampers the application of cemented waste materials in road bases. This...
Performance of Whitetopping in Florida
Since 1988, the Florida Department of Transportation (FDOT) has been monitoring the performance of the first experimental Whitetopping project in Florida for possible implementation as an option for rehabilitation of rutted and cracked asphalt pavements. The project includes three major sections with thicknesses of 150 mm (6 in.), 175 mm...
Continuously Reinforced Concrete Pavement for Combined Tram – Busway in Gent, Belgium
The project concerns the design and supervision of construction for the realisation of a new combined tramway and bus lane linking the main railway station of Gent (Belgium) with the exhibition halls at Flanders Expo. Fundamental criteria for the design included the durability of the pavement, a pleasing appearance compatible...
Maintenance and Comparison of Asphalt and Concrete Parts of Motorways in the Czech Republic
For a long time the professional community in the Czech Republic have been criticizing the fact, that construction, maintenance and rehabilitation of motorways are not systematically studied in light of technology, functionality and reliability in connection with economy of these processes. Therefore the authors of this paper began an R&D...
Green Highways North American Concrete Paving Industrys Perspective
Concrete pavements have long been considered the sustainable choice, simply due to their longevity. There are examples of both highways and local roads in North America where concrete pavements have lasted more than 50 years without significant maintenance. However, recent focus in North America on sustainable development and environmental stewardship...
Dutch Design Tool for Jointed and Continuously Reinforced Concrete Road Pavements
Almost all jointed concrete pavements in the Netherlands, varying from low volume country roads to dual carriage motorways, are designed with the Vencon 1.0 program. The program needed to be upgraded to the Windows operating system. The upgrade also gave an opportunity to reconsider the design models of the old...
Life Cycle Cost Evaluation of Cement Concrete and Asphalt Concrete Pavements in Iran
The pavement is the main and the most important component of a road. Pavements play a major role in the construction cost, maintenance and rehabilitation, traffic quality, vehicle and user costs. They are mainly divided into two types: asphalt concrete and cement concrete. For decision making in choosing the pavement...
Increased Application of Sustainable Concrete Pavements in the Netherlands
Since the late 80ies in the Netherlands more and more cross-sections are constructed as roundabouts in stead of a cross section with traffic-lights. The pavements and prefabricated elements suffer from heavy traffic-loads and lots of maintenance was required. Therefore the last years it is investigated how sustainable roundabouts could reduce...
