The adoption of electric vehicles (EVs) remains low mainly because of its battery related problems, which include high cost, range limitation and weight. Electrified roadways, which allow EVs to charge while they are in operation (motion or stationary) by using Inductive Power Transfer, is a very innovative technology to overcome...
Precast Electrified Roadway Pavement Systems using Engineered Cementitious Composites
Optimal Pore Distribution of Porous Concrete Pavers Aggregate
Concrete pavers are often used for construction of urban area roads as they offer both easy and fast construction as well as high aesthetical value. Although noise reduction is also very important in urban areas, research focusing on low noise concrete pavers is still rare. This paper illustrates a study...
In-situ Architectural Concrete and Pre-Dosed Micro-Concrete for Wear Thin Layer Pavements in Urban Areas Diogo Menezes Square as an Example of Environmental Renovation
In this communication the development of non traditional-solutions for pavement surfaces will be assessed, by the use of colored pre-dosed micro-concrete or in situ concrete in thin layers of high performance architectural applications for urban, pedestrian, cycling and roads. This assessment will be focused on frequently technical constructive barriers inherent...
Evaluation of Excavatable Cement Treated Materials for Urban Areas
For networks owners, like the French national gas utility, it is essential to ensure a rapid access to their installations, even with a simple pick, for normal or emergency maintenance matters. Modular concrete pavements were developed during the last years for that purpose. In order to keep their stability, the...
Fibremix Concrete for Pavements Experimental Search for Maximum Crack-Free Slab Length
Road constructions with fibremix concrete allow longer distances between joints, compared to unreinforced concrete pavements. In the absence of a dedicated design tool for fibremix concrete pavements, the search for a maximum crack-free slab length took place in several projects. Fibremix concrete has been used in parking areas near motorways,...
Experimental Study of Properties of Pervious Concrete Used for Bridge Superstructure
One of the main advantages of pervious concrete is its ability to drain water easily. Moreover, ear-lier studies on pervious concrete have shown that it can be designed to perform well in freeze-thaw regions. Bridge superstructures placed in regions where the temperature during winter time varies around freezing point are...
A New Road with a Micromilled Concrete Pavement and a Bridge Over the Esla River in Leon Spain
The Castilla & Leon Regional Government has built a new road between the towns of Castrofuerte de Campos and Toral de los Guzmanes, located in León Province, in the Northwest part of Spain. It includes a 324m long and 10m wide bridge allowing local traffic to avoid a long detour...
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....
Performance of Pervious Concrete Pavement in Freeze-Thaw Conditions and With Winter Maintenance [No Fines Concrete]
In 2007 the Cement Association of Canada, industry members and the Centre for Pavement and Transportation Technology at the University of Waterloo partnered to carry out a study to evaluate the behaviour of pervious concrete pavement in the Canadian climate. Field sites have been constructed and monitored and laboratory testing...
Evolution of Pervious Concrete Pavement at the Ministry of Transportation Ontario, Canada [No Fines Concrete]
As part of the Ministry of Transportation Ontario (MTO) drive to pursue innovation and have the “greenest” roads in North America, MTO is actively pursuing the use of pervious concrete pavement. Pervious concrete provides many environmental benefits and is recognized as a stormwater management best practice. There is also strong...
Mix Design Method and Void Performance of Concrete for Pervious Concrete Pavement [No Fines Concrete]
Pervious concrete pavement is drawing increasing attention for its high content of interconnected voids which is expected to reduce the environmental impact as concrete is often counted as a causal factor of the urban heat island phenomenon. Performance of pervious concrete can be measured by water permeability, water retentivity and...
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...
