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,...

From some job sites it was reported that the air void content of the hardened road concrete was considerably higher than that of the fresh concrete, especially, when air-entraining agents based on synthetic active constituents have been used. Investigations in the Research Institute with commercial air-entrainers based on synthetic and...

In 2009 the Dutch Parliament amended special laws to speed up road widening projects. This situation opened possibilities for sustainable concrete pavements needing less maintenance, especially for the right-hand lane that takes the heavy traffic. This paper presents the results of a study carried out in 2009, by a working...

This forum addressed design & construction related to Ports & Airports. The range of expert speakers included: Shane Dunstan - Roller Compacted Concrete Pavement Brian Shackel - Interlocking Block Paving Weeks White - Construction & Geotechnical John Knapton - Ports Robert Smith - Airports Bruce Rodway - Airports

Construction of Cement Concrete Pavement on National Highways started in India during the year 1991 when Ministry of Surface Transport, Government of India, under took four laning of 112 Kms. long Delhi – Mathura Section of NH-2. Construction of Cement Concrete Pavement picked up in 1998 with the implementation of...

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...

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...

Multicriteria aid to decision-making is a set of theories and methods designed to assist decisionmakers in selecting one out of several possible alternatives while considering various points of view or “criteria”. In managing their assets, road managers are often faced with the difficult choice of type of surfacing to suit...

The Walloon motorway is the east-west axis in the southern part of Belgium linking the north of France to the southwest of Germany. It was built in the beginning of the 1970’s as a part of the Belgian motorway development program. The design traffic was about 10.000 vehicles a day...

During last years more than hundred kilometres of concrete motorways at the southwest part of Poland were modernised and newly constructed. In the frame of modernisation the old existing concrete pavements, constructed in 30's of last century, were broken-up and the crushed concrete was re-used in new concrete pavement. Newly...

The composite pavement concept can be described as an association of bituminous layers or modular elements with cement concrete. The desired objective is the association of two or more layers of a different nature in such a way that the specific advantages of both types can be profited from thus...

Continuously Reinforced Concrete Pavement, CRCP is a concrete pavement that is reinforced with steel bars in the direction of traffic. CRCP is a durable pavement solution, advancement to plain concrete pavement. Reinforcement is used in CRCP, to tackle the problem of concrete slab cracking, instead of joints used in conventional...
