Since the early 1990s, the design of every type of pavement has been impacted by a major turnaround in Québec Transport Ministry (MTQ) standards. The main focus of this turnaround has been the structural design and the frost protection of every type of pavement, taking into account local climate and...

In response to the growing importance of sustainable building, designers, consultants and pavement managers now tend to make more rational decisions than before when comparing the pros and cons of the construction, maintenance and management of various types of road pavements. Asphalt and concrete pavements offer specific advantages that need...

The pavement is the main and the most important component of a road. Pavements play a major role in the construction cost, maintenance and rehabilitation, traffic quality, vehicle and user costs. They are mainly divided into two types: asphalt concrete and cement concrete. For decision making in choosing the pavement...

Since the late 80ies in the Netherlands more and more cross-sections are constructed as roundabouts in stead of a cross section with traffic-lights. The pavements and prefabricated elements suffer from heavy traffic-loads and lots of maintenance was required. Therefore the last years it is investigated how sustainable roundabouts could reduce...

The rehabilitation of the Ring Road of the city of Antwerp is the largest and most discussed road construction project undertaken in Belgium within the last decades. The Antwerp Ring Road is one of the most trafficked urban freeways of European importance. Six radial freeways are tying into it and...

The properties of concrete mixes produced by replacing the coarse aggregates by milled bituminous materials of the same grading are studied in the laboratory. The milled bituminous material used comes from reclaimed asphalt concrete produced in road maintenance works. The properties investigated are compressive and flexural strength, modulus of elasticity,...

Concrete pavements have long been considered the sustainable choice, simply due to their longevity. There are examples of both highways and local roads in North America where concrete pavements have lasted more than 50 years without significant maintenance. However, recent focus in North America on sustainable development and environmental stewardship...

Concrete pavements which are placed during hot summer weather conditions, harden on the top side, due to the solar radiation, at higher temperatures, as is the case for the bottom side. As soon as the concrete cools down at the top side during the first night, the concrete pavement tends...

The roughness specifications of a recent Israeli PWD concrete road project, consisting of a 4-lanes stretch of a 7- kilometer length (Route No.3), included both bonuses and penalties in their pay-adjustment functions. The California-type profilograph outputs served as the data for these functions. The reason for using this particular profile...

The ‘Drève de Lorraine’ in Brussels is an old forestry road connecting the highway to the south part of Brussels. It has been built in 1925, using concrete slabs of 15 cm thick lying directly on the natural ground. After 78 years of good services, this road has been rehabilitated...

and safety levels for very many years. The Ministry of Transport, Infrastructure and Facilities of the Walloon Region conducted a comparative study of the motorway in 2000 between a continuously reinforced concrete pavement and a bituminous pavement. Very many factors obviously come into play for an objective comparison and they...

Development of new types concrete technology caused an increasing of concrete mixture production with a high proportion of fine filler in recent years. Fine filler is used to ensure required concrete mixture rheology qualities, which are needed to the concrete mixture storage into boarding. There are several materials can be...
