In this paper some roads and industrial pavements where "semi-continuous concrete" was employed are prcscntcd as well as cost and performance under several conditions.

Revision of the Austrian Design Method for Standardised Concrete Pavements
The Austrian specification for pavement design also contains standardised construction types for concrete roads. After more than 10 years of experience with the application of these standard pavement types the specification has been revised comprehensively with a special focus on the following objectives: - establishment of an improved method for...
Adjusting the Moisture Content of Mature Concrete for Durability Control
The presence of a specified volume of definite-dispersity air voids in the structure of cement concrete does not quarantee the scaling-resistanceIr concrete pavements under the action of frost and deicing agents. Experiments show that partial drying of mature concrete before its saturation increases the concrete scaling-resistance, while conipleLe dLyirlg up,...
Joint Load Transfer Testing
The paper describes and evaluates plate hearing tests performed on airfield CC slabs, in order to ascertain the interaction of slabs across transverse and longitudinal joints and the joint load transfer. The applied characteristics of mad transfer I .T and T ,TF, varied, however. the great significance of temperature and...
Loading Test on the Surface of Concrete Slabs Cast on Senii-Rigid Base Course
In China, the semi-rigid base materials, with relatively higher strength and modulus, have been widely used in the construction of high-grade roads in the recent decades. However, present specification' for structure design of concrete pavement is based on the results of tests made on the more flexible roadbase. According to...
Test-Methods on Road Concrete with a Very Porous Structure
Research is carried out in the Magnel Laboratory - Ghent University into the properties of road concrete with a very porous structure, enriched with polymer emulsions. The aim of the tests is to optimise the composition of the porous concrete. In this context, the choice of the type of polymer...

The French Architectonic Concrete Paving Development
This paper present the good possibilities that we can expect with exposed aggregate concrete surfaces
Consideration of Some Factors Affecting the Competitiveness and Potential for Future Use of Concrete Roads in the UK
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...
Improvement of the Temperature-Shrinkage Crack Resistance in the Construction of Concrete Road Pavements
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.
Whole Life Costing
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....
The Dutch Visual Inspection Method and Standards for Levels of Maintenance of Concrete Roads
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...
