Advancing the Use of Continuously Reinforced Concrete Pavement in the USA
The use of continuously reinforced concrete pavement (CRCP) is enjoying a renaissance in the United States (USA). CRCP has the potential to provide a long-term, zero-maintenance, service life under heavy traffic loadings and challenging environmental conditions, provided proper design and quality construction practices are utilized. In the USA, the Federal...
Quality and Optimal Grading of Sand for Optimal Performances of Concrete Pavements
The quality of sand influences in every way the quality of concrete and affects, among others, the workability, the durability as well as the mechanical strength of concrete. It is acknowledged that a sand of good quality to be used in concrete pavements must contain few fine grains and be...
The Vecu Process for Roadways Public Spaces and Urban Development Projects a New Approach for Consolidating the State of the Art
Urban roadways and public spaces are major fields of application for road concrete in France. Specialised contracting firms have gradually refined the finishes, skills and techniques to provide an extensive range of decorative concrete models. A collaborative process known as VECU (French acronym for roadways, public spaces and urban development...
Progressive Composite Bridge Construction with Cement Concrete Pavement
The project deals with research on effective composite steel and concrete bridge structures, profiting from directly running cement concrete pavements. The aim is an innovative layout solution, technology of construction and maintenance and research of new formulas for concrete parts which will lead to lower collective costs of production and...
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...
Concrete Pavement Preservation Integrating Engineering Application and the Environment
Concrete Pavement Preservation (CPP) is a series of engineered techniques developed over the past 40 years to manage the rate of pavement deterioration in concrete streets, highways and airports. CPP is a non-overlay option used to repair areas of distress in concrete pavement without changing its grade. This rational, preventive...
First Experience of Diamond Grinding Concrete in Mexico
The surface condition of a pavement is a factor that may vary due to the influence of traffic and construction methods, and is a functional characteristic that impacts the road user considerably. For concrete pavements in good structural condition, diamond grinding can be a highly effective and economical choice for...
Splitting Tensile Strength of Concrete Road Slabs – A Key Property for Load Capacity and Durability
Concrete pavements are continually subject to the effects of weather and traffic. These may cause tensile stresses at the top and bottom of the concrete road slabs. The resistance of the concrete slab to such effects depends on a large number of factors. In particular, the concrete tensile strength and...
Early and Late Age Shrinkage of Concrete in Industrial Floors Design
For proper joint design, slabs size and slab thickness of concrete industrial floors, as well as other structures, it is necessary not only to know the final shrinkage of the concrete, but also the evolution over time for both long term and early shrinkage, and the relationship between these properties...
The Influence of Sand Grading on the Air Void System
In this research the influence of sand grading on the air void system in mortar is determined. Three sand grading types are defined: sand low, sand mean and sand high. The difference is the amount of fines, < 250 ?m, (low, mean and high amount of fines) in the sand....
Guidelines for Bus Stops in Concrete in the Netherlands
New legislation for improving accessibility to buses by people and especially disabled people led to the modification of bus platforms and particularly the kerbs at these platforms. Buses should be able to approach quite close to these platforms. This depends on the design of the bus stop area. The dimensions...
