A mobile measurement system was used to quantify the relative importance for the road dust particle emissions on highways with concrete and stone mastic asphalt (SMA). Studded and non-studded winter tires were tested at 70, 90 and 110 km/h. The measurements were performed during October on dry, clean roads. Both...
Modern SFHC Super Fast Hardening Concrete Repair System for Airfields and Roads, Based on Special Cement for Infrastructure Projects
The importance of fast traffic area repairs is increasing. For roads and airfield service areas a specific fast repair system has been developed to satisfy the demand. This system uses standard methods of ready-mixed concrete and is appropriate if a few additional requirements are taken into account. The placing is...
Concrete Bus Lanes
Cities worldwide are facing problems of traffic congestion in their centres and suburban areas as well as on access roads. In densely populated countries like Belgium and the Netherlands this phenomenon also occurs on roads linking cities. Because of these mobility problems and the serious impact on the environment, decision...
Posibilities of Concrete Pavement Blocks
During the last years precast concrete pavements have increase their market. The main reason of this success is the large amount of possibilities which offer to the client. Maintaining the best mechanical properties precast pavements can give to the designer the freedom necessary to create singular environments, and what is...
Latest Findings on the Construction Type Continuously Reinforced Concrete Pavement
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...
New Hungarian Regulations for Concrete Pavements and their Application in Hungary
The first concrete pavement was built in Hungary with ABG slip form paver on motorway M7 between Budapest and Lake Balaton. After 30 years, concrete pavement was built again on the Motorway M0 around Budapest. The limited performance capacity of asphalt pavements on expressways and motorways made it necessary to...
