The mechanical adherence properties of new concrete bound with old concrete surfaces which had been pretreated in a conventional manner as well as with new techniques, have been studied uding fracture mechanical methods. It was shown that far better adherences are achieved with specially structured old concrete surfaces than with...

In 1991 a concrete rut filling on an old concrete pavement at the highway E-1 8 in the southern part of Norway was performed. The rut depth, caused by studded tyres, had reached 23 mm, and the pavement required rehabilitation of the ruts. The intention with the filling was to...

Extensive rutting exists on many high volume traffic roads in Sweden. Traditional maintenance means asphalt resurfacing every second or third year. Adding a thin high strength concrete overlay would prolong the service life of the repair due to the high wear resistance of this kind of overlay. To study the...

This paper describes the Swedish experience with thin concrete overlays on old rutted concrete roads. In Sweden, the use of studded tyres leads to wedi and rutting on highways with intensive traffic. In the late seventies, some concrete roads were built in the South of Sweden. A thin concrete overlay...

The M20 motorway between Junctions 3 and 5 near Maidstone (UK) is an unreinforced pavement with joint spacings of 5m and 6m, comprising warping joints with contraction joints every 30m. The pavement was constructed at the beginning of the 1 970s. A contract for maintenance between Junctions 4 and 5...

The "technique of thin bonded overlays" has been applied to restore damaged concrete pavement surfaces. In this article results from laboratory tests concerning different combinations of repair mortars and several support concretes are piesciuted and discussed. Bond strength of the overlay to the supporting concrete has been assessed by means...

The motorway A7, also called the "Motorway of Wallonia", was opened to traffic in December 1970. In the vicinity of Mons this motorway carries a very high volume of heavy traffic, which is still increasing. The right-hand (slow) lane is subject to severe rutting, which has affected the deeper layers....

Many areas in western Europe suffer trom congestion of traffic during peak hours, mainly on motorways leading to and situated near the economic centres. Therefore, authorities plan to widen several motorways in order to improve the mobility. In the Netherlands the widening of approximately 400 km motorways is expected to...

To improve the surface quality or the water drainage and the service life of a mediocre damaged concrete pavement, this pavement can be overlaid with a 4 to 6 cm thick asphalt layer. The status of the concrete pavement and of the joints with respect to potential reflection cracks needs...

A project for a building sliuuld include a forecast obout the longtime behaviour. With the cost benefit analysis the technical longtime behaviour can be expressed in figures. In the case of the road pavements these costs are costs for the government and for the road users. The estirlIdLiull can be...

In this paper we discuss about how to select the best pavement type to minimize the pavement cost. It is studied which pavement type (flexible or rigid pavement alternatively) is more suitable for Turkey taking into account economic criteria. The most important parameters for choosing the type of pavement are...

This paper considers the role of whole life costing in the management process for the road network and explores the background to current interest in England. It describes the development of the computer model, COMPARE, for assessing the whole life costs of bituminous and concrete pavement options. The key components...
