Design

The long service life of cement concrete roads, as well as the new objectives of contracting authorities taking into account significant extensions in hypotheses on the design service life of roads, streets and runways, oblige the technical civil engineering community to plan much more than in the past for the...

A Removable Urban Pavement (RUP) is a pavement that can be open and closed rapidly, with light facility, for an easy access to underground networks. It has the same difference with a conventional road as a window compared to a solid wall. No such a pavement seems to have ever...

Construction of Cement Concrete Pavement on National Highways started in India during the year 1991 when Ministry of Surface Transport, Government of India, under took four laning of 112 Kms. long Delhi – Mathura Section of NH-2. Construction of Cement Concrete Pavement picked up in 1998 with the implementation of...

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...

Pavements on bridges are a very problematic element for each road administration. Classic European solution, concrete bridge deck with waterproofing membrane and pavement with asphalt wearing course, makes a lot of problems with maintenance, road closures etc. The paper presents results of research in the field of concrete pavements on...

A recently finished study at the Research Institute of the Association of the Austrian Cement Industry and the Institute for Road Construction and Maintenance, Technical University Vienna focuses on the improvement of the joint design on concrete roads. The main issues of this study are presented in this paper. Special...

New structural design software is presented that deals with flexible, composite and rigid structures. The pavement design is based on a trial-and-error process involving the use of the linear elastic multilayer model for flexible and composite pavements (Burmister's theory) and the strength of materials (Pasternak’s theory) for the rigid ones.

Recycling techniques to take profit of materials from existing pavements are being increasingly used, due to different technical, economical and ecological reasons. Therefore, the Technical Committee C7/8 on Pavements of PIARC (World Road Association) has prepared three guidelines dealing respectively with hot recycling in plant of bituminous mixt ures cold...

A greatly increased air void content in the hardened concrete has been found in recent years in some contract sections of concrete pavement. Investigations were carried out at the Research Institute of the Cement Industry on road concretes in order to determine the reason for this excessively high content. The...

The needs of road managers cover a number of sometimes conflicting aspects, which have to be reconciled. These relate to the durability of the works, their flexibility of use and reuse, their ease of maintenance and of course their long term cost. They also relate to the safety of the...

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...

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...
