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...

“Photocatalytic” materials are discussed for various applications in building technology ranging from de-soiling to de-polluting applications. However most of the efficiency proofs are derived from indirect laboratory scale tests. Italcementi Group has developed a range of cement-based products based on the TX Active? concept demonstrating both photocatalytic activity and performances...

The record of the first concrete road construction in India dates back to 1914. However, till the end of eighties, cement was a scarce commodity in India; therefore, concrete road construction was relegated to the background. After liberalization of cement market, concrete roads staged a comeback and in the nineties...

Superbus is an innovative new concept in personal public transport, developed by the Delft University of Technology. The Superbus consists of a highly advanced vehicle that can reach speeds up to 250 km/h a special Supertrack Infrastructure and advanced IT applications for services on request, road handling and comfort and...

Increasingly plastics become the material of choice by product designers because they provide useful properties and for this reason the worldwide production of plastics is growing year after year. At the European level the reference concerning the recycling and reuse of waste plastics obliges Member States to recover and recycle...

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...

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 this paper the results of laboratory investigation preceding realization of continuous prestressed concrete pavement at Krakow – Balice Airport are presented. Three concrete slabs of dimentions 1.0 m × 3.6 m × 0.16 m were realized in the Laboratory of Technological University of Krakow. Two of them were prestressed...
