The main difference between pavements and other elements made of concrete is the surface property. The surface in concrete pavement must be finished properly. It has been known for a long time that air-entrainment can be used against freezing and thawing deterioration of concrete pavement slabs. In the freeze-thaw attack,...

The paper presents the results of a study about the use of recycled tire and building materials in concrete for “whitetopping” on asphalt concrete paving. This report presents the results of laboratory experiments and field tests. These results were obtained with concretes using substitution ratios of 15% to 20% by...

The fast development of car technology has caused a steady increase in the speed of vehicles and increasingly higher demands on braking and traction. International studies show that every increase in average speed causes increase in personal injury accidents. Yet the present transport infrastructure in general and cement concrete pavement...

The paper describes an application of ultra-thin white-topping on a bituminous factory pavement. Different road cement concrete mixes were studied: high-strength concrete, concrete with PP fibres added, concrete modified with latex, concrete made by tyre-rubber grains instead of natural aggregate and steel fibre reinforced concrete. The binder was CEM II/A-L...

In 1999 - in the province of Noord-Brabant in the Netherlands - an eighteen-year-old asphalt road with a cementstabilised fly-ash road-base, appeared to be in bad condition. Further investigation showed that the base was almost completely disintegrated, probably due to bad drainage and due to a possibly low cement content....

surfaces, which is a product developed by the BRRC (Belgian Road Research Centre) and Febelcem (Federation of the Belgian Cement Industry), it became clear that it would be necessary to conduct onsite validation in the area of rigid roads. In particular, the various hypotheses regarding the effectiveness and durability of...

CROW published in 2001 in the Netherlands the new national methodology on Pavement Management Systems on asphalt, block pavements and concrete roads. DHV has been the author of this publication. Two major improvements are implemented in this new methodology: 1. concrete pavements are fully included 2. a connection has been...

The paper gives an overview on an on-going R&D project carried out by LCPC (France). The aim is to develop a purely hydraulic road structure in accordance with modern infrastructure requirements, which may also be used to rehabilitate old rigid pavement. The High-Performance Concrete (HPC) carpet consists in building a...

Serviceability of the concretes that undergo such effects of repetition of freezing-thaw is greatly affected by water-cement ratio, permeability, composition of the cement and mineral additves. Water-cement ratio being between 0.40-0.50, the concrete having a structure without any voids, using a cement with mineral additives, increase the resistance of the...

The study was conducted to bring out the salient features of blended cements, which go a long way in establishing the durability of rigid pavements. Blended cements not only enhance the life cycle of concrete road by protecting it from chloride and sulfate attack but also reduce the thermal cracking,...

This paper presents results of study on evaluating durability and permeability of porous cement concrete pavement by accelerated loading test at PWRI pavement test track. The following procedure was conducted to evaluate the durability and permeability of porous cement concrete pavement. Three test sections were constructed in 1997. These sections...

The Zuidtangent is a free high quality public transport lane between the city of Haarlem and Schiphol Airpoprt. The full trajectoryi s built in continouusly reinforced concrete. In this paper some design aspects are described. Also the use of concrete as a wearing course on bridges and in tunnels is...
