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...

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,...

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...

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...

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...

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...

Block or slab pavements with concrete or natural stones are mainly used for communal areas, where a variety in creation is welcome, but also the lifespan of the pavement is very important. At pedestrian precincts, which are also trafficked by trucks, often high vertical and horizontal loads occur. If the...

In order to increase knowledge of how fuel consumption corresponds to pavement type, the Swedish National Road and Transport Research Institute (VTI) was commissioned to investigate the difference between asphalt and concrete pavement surfaces. Measurements were made north of Uppsala, Sweden; where a motorway section included both types of pavement....

On 19 May 2006, the Premier of the Gauteng Province in South Africa announced the project: “gravel roads to surfaced roads, stormwater drainage and walkways projects within the top twenty townships (20T Project)”. The main aim of the project was to improve the living conditions of communities in previous neglected...

A safe and durable concrete barrier has been built on the A73 in the southern part of The Netherlands (Province of Limburg). The decision to install this barrier was based on consumer-focused networking. The benefits of concrete barriers were illustrated during the networking process, including the prevention of break-through and...

The cyclo-pedestrian footbridge built at the beginning of 2009 over the former L160 railway line in Brussels (Auderghem) consists of a 58-metre long reinforced concrete slab (cross-section 4.50m x 0.30m), “chaotically” supported by 37 wooden stilts (Douglas Fir). Its horizontal stability is ensured by two concrete abutments; the stilts, ball-and-socket...

Improvement or stabilization of soils in subgrade by using lime or binders can provide significantly improved engineering properties. The results of soil improvement can be very substantial increases in resilient modulus values, in shear strength, continued strength gain with time even after periods of damage and long-term durability over decades...
