In 2007 the Cement Association of Canada, industry members and the Centre for Pavement and Transportation Technology at the University of Waterloo partnered to carry out a study to evaluate the behaviour of pervious concrete pavement in the Canadian climate. Field sites have been constructed and monitored and laboratory testing...

As part of the Ministry of Transportation Ontario (MTO) drive to pursue innovation and have the “greenest” roads in North America, MTO is actively pursuing the use of pervious concrete pavement. Pervious concrete provides many environmental benefits and is recognized as a stormwater management best practice. There is also strong...

Pervious concrete pavement is drawing increasing attention for its high content of interconnected voids which is expected to reduce the environmental impact as concrete is often counted as a causal factor of the urban heat island phenomenon.  Performance of pervious concrete can be measured by water permeability, water  retentivity and...

Recent years have witnessed the significant development of public surface transport systems: in our cities: tramways, systems on tyres, right-of-way bus corridors, etc. This phenomenon is a response to the high stakes involved for mobility and communication in urban areas. These projects have seen the emergence of new problematics related...

CROW published in 2001 in the Netherlands the new national methodology on Pavement Management Systems on asphalt, block pavements and concrete roads. DHV has been the author of this publication. Two major improvements are implemented in this new methodology: 1. concrete pavements are fully included 2. a connection has been...

Questions regarding the environment are being particularly felt in certain countries, and noise con-trol requirements have led to the development ofthin free draining materials able to limit tirepavement contact noise.We shallbe dealingherenotwith a thin free draining pavement structure, butwith a porous concrete pavement of 40 cm thick-ness. Theoretical studies have...

Over the past few years, interest in the uses and applications of porous cement concrete for pave-ments has been growing. Its position in pavementconstruction has developed to such an extent thatit iscurrently used in places of greater importance(from shoulders to sub-bases, and even surfaces).This paper is part of the experience...

In areas with a low bearing capacity of the soil it is very hard nd expensive to manage and maintain the road system. In eneral the common pavement structures are not able to resist uring its lifetime the deformation of the subsoil caused by the eavy weight of pavement structures....

Concrete made with a superplasticiser has been used in Germany in the field of paving since the middle of the seventies. If these concretes of high workability show a high strength at a young age, they are called high early strength. These concretes can be subjected to high loading on...

In the eighties, a campaign was set up in Belgium in view of the rearrangement of the state road sections which are passing through built-up areas. These projects were meant to improve the road safety and the viability along these cross town links. Efforts were made to come to a...

This paper deals with the problem of thickness design of low-volume roads. It examines the possible use of tables of minimal thickness or analytical methods, especially developed for low-volume roads (as in France and Belgium). Attention has been paid to realise the influence of design factors, such as traffic and...
