In areas with a low bearing capacity of the soil it is very hard nd expensive to manage and maintain the road system. In eneral the common pavement structures are not able to resist uring its lifetime the deformation of the subsoil caused by the eavy weight of pavement structures....
Superplasticised Concrete For Urban Paving
Concrete made with a superplasticiser has been used in Germany in the field of paving since the middle of the seventies. If these concretes of high workability show a high strength at a young age, they are called high early strength. These concretes can be subjected to high loading on...
The Passage of State Roads Through Built-Up Areas. Applications of Concrete Block Pavements
In the eighties, a campaign was set up in Belgium in view of the rearrangement of the state road sections which are passing through built-up areas. These projects were meant to improve the road safety and the viability along these cross town links. Efforts were made to come to a...
Design of Low-Volume Concrete Roads. Tables Or Analytical Procedure?
This paper deals with the problem of thickness design of low-volume roads. It examines the possible use of tables of minimal thickness or analytical methods, especially developed for low-volume roads (as in France and Belgium). Attention has been paid to realise the influence of design factors, such as traffic and...
Light-Traffic Roads in France Towards New Practices
Decentralization has brought about significantly renewed interest in France in investments for regional and local roads, their rehabilitation and maintenance. Many methodological tools have been developed in the past 10 years to prepare and accompany these trends in areas in which cement concrete had played a sinall relative part in...
Payement Management For Concrete Pavements
The Illinois interstate highway network includes over 1700 centerline miles of jointed concrete and continuously reinforced concrete pavements. The pavements were constructed beginning in the 1950's through the 1980's and represent a wide range in designs and traffic loadings. This large highway network is now requiring extensive rehabilitation work as...
Cement Concrete Secondary Roads Management Using the Belgian Road Research Centre Gersec System
A pavement management system for secondary road networks has been developed by the Belgian Road Research Centre for local government agencies and municipalities and handles both cement concrete and bituminous pavements. The system called GERSEC integrates technical approaches and economical evaluations with a view to optimize the distribution of the...
Evaluation of Existing Pavements and Conçrete Overlay Design in the Netherlands
Working Committee «Overlay in concrete» is founded to create a manual containing practical methods for designing and building concrete overlays for road and airport pavements for Dutch conditions. Results of the Working Committee activities are presented in this paper. A method to determine the bearing capacity of existing pavements is...
Very Thin Surfacings For Improving Skid Resistance of Concrete Pavements
This paper describes work on the skid resistance properties of some fine aggregates available in Indiana, as an attempt to improve the driving safety characteristics of concrete pavements. In this work the British Polishing Machine and the Portable Skid-Resistance Tester were used for laboratory evaluation of some mortar mixes. Aggregates...
