In 1920, the first Continuously Reinforced Concrete Pavement (CRCP) was constructed in the USA. In Europe, this type of construction was first applied in Belgium in 1948. Since then, more than 50.000 km of CRCP have been built in more than 30 countries. These implementations have shown increased driving comfort,...
Initial Cost Comparison of Rigid and Flexible Pavements: Under Different Trafic and Soil Conditions
In this paper, the economic analysis has been done on both flexible and rigid pavements. These cost analyses play a great role on the decision-making stages in selection of pavement types. In this analysis initial cost of rigid and flexible pavements have been determined for both flexible pavements and rigid...
Effect of Pavement Type on Rolling Resistance and Fuel Consumption of Heavy-Duty Vehicles
The purpose of this study is to research the influence of fuel consumption of heavy-duty vehicle for concrete pavement and asphalt pavement respectively. It was decided to adopt a new approach for vehicle fuel consumption -- measurement of the running resistance of vehicles to investigate their rolling resistances due to...
Durability of Exposed Aggregate Pavement
In recent years, exposed aggregate concrete has been used increasingly for the construction of the top surface of concrete pavement in Germany. Following placement, the fresh concrete surface is usually sprayed with a combination of a retarder and a curing agent (first curing). Depending on weather conditions and concrete composition,...
Durable Futuristic Roundabout in the City of Eindhoven, the Netherlands
The main traffic entrance to the city of Eindhoven is the connection with the surrounding A2 Highway. This entrance of the city is a large two lane roundabout with a diameter of 97m.A lot of heavy trucks use this roundabout. The asphalt pavements of this roundabout showed severe rutting, cracks...
Roundabouts in Continuously Reinforced Concrete Design Construction
In Belgium, as in many European countries, traffic at major junctions is managed increasingly by constructing right-of-way roundabouts, which allow safer and smoother traffic flow. The intense heavy traffic at these roundabouts induces extreme stresses in the pavement, both as a result of centrifugal forces as well as the overloading...
The Belgian Code of Good Practice for Soil Treatment with Lime and Hydraulic Binder Update
In 2004, the Belgian Road Research Centre published some documents concerning soil treatment with lime and/or cement to make them suitable for use in road applications: a code of good practice including theoretical and practical knowledge and 3 practical guides to specific applications (soil improvement for trench backfills, soil stabilization...
Measurement and Effect of Dowel Bars Alignment in Concrete Pavements
The precision and applicability of two non-destructive measuring methods for dowel bars alignment: Ground Penetrating Radar (GPR) and the Pulse Induction method (PI). was investigated. The project was sponsored by the German Federal Ministry of Transport, Building and Urban Affairs (Bundesministerium für Verkehr, Bau und Stadtentwicklung BMVBS). The...
Continuously Reinforced Concrete Inlay at Townhill Compulsory Truck Stop
The aim of this paper is to present an overview of the construction of a continuously reinforced concrete inlay at the compulsory truck stop on an interstate freeway: National Route 3, Section 3, km 20.0. The truck stop is situated in a truck lane on the southbound carriageway of the...
European Long-Life Rigid Pavement
The European Long-Life Pavement Group (ELLPAG) was formed in 2000 as a working group by the Forum of European National Highway Research Laboratories (FEHRL) members, under the auspices of the Conference of European Directors, to report the current state of knowledge on long-life pavements in Europe, in particular on the...
Concrete with Exposed Aggregates Experiences in Germany
Concrete road surfaces with useful properties and a long useful life have been constructed for many decades, but further development is still required due to changing boundary conditions. Here, the important challenges are the increase in traffic load as well as specific requirements to traffic safety, environmental compatibility and economic...
Mechanical Characterisation of Cement Bound Mixtures with Waste Foundry Sand and C&D Aggregate for Road Pavement Foundations
In recent years, a new material has been experimented in Italy for road pavement foundations. It is a mixture made of Waste Foundry Sand (WFS) and Construction and Demolition (C&D) aggregate, water and CEM 32.5R cement, the performances of which can be compared to those of traditional cement bound granular...
