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...

This paper describes a structural design method developed for composite pavement which is composed of an asphalt surface course (ASC) and a continuously reinforced concrete base course (CRCB). The design method is based on the fatigue analysis of CRCB. In the analysis, loading and thermal stresses in (2RU13 are calculated...

High performance concrete - HPC - is characterised by high strength and considerable durability under high service load. In highway construction these concrete is used to constructing and very rapid repairs of pavements, bridges, viaducts and tunnels. Differentiation in types of such objects as well as erection conditions and than...

ECOPAVE is a system of laying concrete through a modified bituminous paver, inducing transverse cracks into the concrete, and overlaying with a thin bituminous surfacing. The system has been developed through a BRITE project with partners in the UK and Denmark. It is coiisideied to provide economic benefits over the...

On the European route E35 near Utrecht in the Netherlands a new highway section has been built. The authority in charge has chosen a continuously reinforced concrete roadbase. A monitoring program has been started to collect data from the pavement behaviour. The data will be used fnr rnmparing the chosen...

In an effort to tackle road traffic noise, research into quieter road surfaces has included trials of a new type of concrete surfacing called exposed aggregate concrete, which has been used in a number of other European countries. Two trials of exposed aggregate concrete have been constructed in the UK;...

The Netherlands are a flat country, where the bicycle is a good alternative for short and midrange transportation. The government tries to encourage the use of a bicycle by improving the bicycle infrastructure, thus trying to reduce movements by car. Bicycle pavements are managed at a local or county level....
