The use of high performance concrete (HPC) is becoming more popular in the United States. Many State Departments of Transportation are replacing conventional concrete especially with HPC bridge decks. Despite the growing popularity of the material, little is known on the effect of the available curing methods on the mechanical...

For the last ten years, new composite pavement structures have raised a significant interest. Based on the association of a concrete layer bonded to an asphalt sub-base, they lead to a reduction of the layers thickness and cost. A long-lasting bond is essential. This paper focuses on the mechanical study...

In the period 1996 — 2001 the ”Zuidtangent" was designed and constructed. The "Zuidtangent" is situated between Haarlem and Amstelveen, just south of Amsterdam (The Netherlands). The "Zuidtangent" is designed as a special purpose road connection for public transport and plays a major role in the accessibility of the Schiphol...

A comparison of "capital plus maintenance" costs has been made in France using the following methodology: - firstly, a comparison of sections of concrete pavement with conventionally constructed ones of the same age on the same stretch of road, - secondly, a statistical analysis of the performance of the different...

Experimental and theoretical investigations on deformations and stresses in concrete pavements subjected to realistic weathering conditions have been carried out. On large-size concrete slabs critical hygral and thermal loadings with boundary conditions corresponding to different field situations were simulated. The results of the experiments served to calibrate and to verify...

This paper is based on a research project, which has covered the importance of high range water-reducers (HRWR) on properties and consequently on quality of concrete. More precisely deals with the influence of six HRWR of an amount of twelve which were tested. They have been prepared concrete mixes with...

This paper presents a laboratory-based mix design method for roller compacted concrete pavements for optimizing their cost-performance. It consists in introducing a new design procedure based on laboratory tests for aggregates, sand/gravel ratio, cement/water ratio, cement content, and resistance of the specimens to compression and flexion, in order to establish...

Over the past years, consideration was given to the damage some streets were exhibiting which had been constructed from porphyre cobblestones paving or concrete block paving. The director of the street accomodation for the region of Brussels took the decision to replace those damaged areas with an Imprinted Concrete Paving...

In 1996 a new pavement structure was launched in France under the name « Béton de Ciment Mince Collé (thin composite whitetopping) », BCMC. This technique was an adaptation of the Ultra Thin Whitetopping (UTW) developed in the USA since 1990. But while in the USA this technique was mainly...

and to secure the height position of the individual slabs. They must be positioned in the middle of the slab thickness so that they do not prevent longitudinal motion of the slabs. In modern concrete pavement construction the concrete is poured over the entire cross section width using slip form...

The intention of this paper is to shed light on the interaction between road roughness and the resulting road damage caused by static and dynamic wheel forces. For this purpose several trucks have been mathematically modeled as multi-body systems in great detail. The models are based on actual data of...

Alstom who is a major company in the turnkey railways construction activity including railways track construction, developed an adaptation of roads and highways calculation modelization based on concrete fatigue resistance under traffic loads to for railways tracks calculation purpose. Roads and highways have a long and rich experience and data...
