The street is not a road because it fulfils multiple functions as a travel, social, cultural and economic space. The choice and organisation of surfacing play an important role, which must be clearly identified by roadway players. Cement concrete in all its urban forms occupies a place of choice in...

The skid resistance of a road surface is of high importance for road safety. All kinds of controllable acceleration, deceleration and steering actions are only possible, if the road surface offers at least the same adhesion as the driver’s action requires. It gets even more difficult due to the fact...

The Administration of the Ministry of Equipment and Transport of the Walloon Government, together with researchers of the Federation of the Belgian Cement Industry and the Belgian Road Research Centre, put into practice a software program for the structural design of pavements. This program is in use for several years...

Due to severe freeze thaw salt damage to concrete pavements on military airfields in the Netherlands, the Agency for Infrastructure of the Netherlands Ministry of Defence (DGW&T) decided to prescribe ordinary Portland cement (CEM I 32.5R, coded as PC) with air entrainer. The ENCI (First Dutch Cement Industry) is of...

For the rehabilitation of rutted asphalt pavements white topping and ultra thin white topping turned out to be adequate methods. The force-fit bonding between asphalt and concrete is a pre-condition for the functioning and durability of this method. Little attention is paid on testing of the bonding; in the majority...

The joint system presented herein takes advantage of the natural development of shrinkage in concrete to induce the formation of joints along the projections of previously placed system devices. Such system induces in an in-situ concrete pavement an efficient interlocking indentation among the slab elements resulting from the shrinkage phenomenon....

Early in 2005 the “Steenokkerzeel bypass road” was opened for traffic. This road forms a type of ring road around Steenokkerzeel centre. This new road was linked to the centre via roundabouts in two places. The bypass road as well as both roundabouts were laid in continuously reinforced concrete, the...

Design and construction of road intersections in the form of roundabouts is getting more and more popular not only in urban areas but also on highly trafficked primary rural roads due to their high road safety potential. Well designed roundabouts show improved safety characteristics by reducing the number and, particularly,...

The High Plateau (known as Altiplano) in Bolivia has unique climate. The high altitude, over 4000 m above sea level, relative humidity, as low as 20% and daily temperature ranges between 25° C max. day down to – 10°C at night during winter time, impose special construction processes for concreting...

Heterogeneous photocatalysis is a rapidly developing field in environmental engineering. It has a great potential to cope with the increasing pollution by traffic. The addition of a photocatalyst to ordinary building materials such as concrete, creates environmental friendly materials by which air pollution or pollution of the surface itself can...

Since 2001 the design with an interlayer of geotextiles is a standard structure in the German pavement catalogue RStO 01. Geotextiles shall guarantee uniform, elastic support of the concrete slab, hence reducing stresses due to temperature and moisture gradient, reduce pumping processes and prevent an origination of reflection cracks from...

The design period of pavements in Austria is in general defined with 20 to 30 years. According to the Austrian standards and guidelines for pavement design the design life for bituminous roads is 20 and for concrete roads is 30 years. Looking at existing roads, it can be recognized that...
