A New Geometry of Airport Concrete Pavements

This paper present the good possibilities that we can expect with exposed aggregate concrete surfaces

Although concrete roads have traditionally been used in the construction of a small part of the UK network, there is continuing interest in the potential for concrete pavements. Consideration of the way in which whole life cost (WLC) may influence selection of the most competitive form of concrete structure when...

Measures of increasing the crack-and frost resistance of a cement concrete pavement are presented in the paper: -use of control joints in the fresh concrete, only placed in the morning time; - increase by20% of the amount of plasticizer, mixing duration and compaction time of concrete mix.

is important to have the knowledge about the connections between different costs and different surface characteristics of a pavement. The costs are for the road, traffic safety, road user and environment etc. The surface characteristics are things like friction, micro- and macro structure, iuts, evenness, cracks, sloping and drainage etc....

In view of the evaluation of the Pavement Management System used in the Netherlands, this system will be made suitable for concrete pavements. Thcrefore two main elements of thp cyctem, the visual inspection method and standards for levels of maintenance for concrete pavements has been developed. The visual inspection method...

The evaluation and control of vibrations induced in the environment by the road traffic is a problem of increasing concern mainly in urban areas. Several solutions are under development to define pavement structures capable of absorbing traffic vibrations so to reduce the impact on the environment surrounding the road infrastructure....

The examined computation procedure for self-locking concrete block pavements is based on the ordinary methods adopted for the computation of flexible and semi-rigid pavements. These methods consider a stress and silaiti distiibutiou uiidei design loads. The analysis considers both the classic, elastic multilayer model, and an axisymmetric, finite element model...

ratios between 1.0 and 1.25 to achieve the proper performance of the slabs designed. It is clear that thickness of slabs has to be properly designed according to the operations foreseen for the term of use. In the case of rehabilitations by way of overlapped layer, this has rendered a...

The turnkey construction method can be very beneficial to an employer both during the bidding process and during construction. A turnkey road construction project was selected for the first time in Germany as the construction method for the A15 motorway between Cottbus-West and Forst. In order to alleviate backups within...

Road concrete in the thirties did not have a particularly high strength, but it grew over the years. Strength tests on cores, taken last year, show that the strength -compressive as well as the more important splitting tensile- of the old section and also of almost all new ones is...

Between 1982 aiid 1989, 8 thin overlay test sections were constructed with a total surface area of 129.000 m2 . The relevant research project is carried out with a view to the necessary future renovation of part of the Belgium road network. All sections were built with 10 to 12...
