COST 324 aims to integrate current pan-European studies on the long-term performance of road pavements under the influence of traffic loading and climate. It will thus provide guidance to decision-makers, aimed at ensuring that improved pavement design and management, based on observed pavement performance, will result in a more cost-effective road network, with reduced traffic congestion due to maintenance operations.
- Assessment of the factors affecting pavement performance.
- Creation of an inventory of real time and accelerated load testing programmes at national level.
- Assessment of current performance prediction models.
Establishment of terms of reference for:
- European performance prediction models
- a centralised pavement performance database at European level
- acquisition of traffic and axle load data
- Establishment of common procedures for the acquisition of pavement performance data.
- Creation of a centralised pavement performance database at European level.
The highway network in Europe will have to carry larger volumes of traffic and increasing axle loads in the years to come. If no action is taken at European level, pavement failure and maintenance problems will increase significantly.
The European pavement engineering profession is ahead of worldwide competition in the development and use of analytical techniques for the design of new pavements, and for pavement management. Full implementation of this knowledge is, however, severely hampered by a lack of co-ordinated performance data in this area. A number of European countries are therefore now addressing this weakness.
Benefits to Different Users
The scientific users of the results of COST 324 are researchers in the field of pavement management. The project will generate the basis for a full-scale European experiment and analysis to establish European pavement performance equations to be carried out under the Transport Programme of the Fourth Framework Programme for Research and Development.
Pavement performance equations form the core of pavement management systems (PMS). The professional users of such systems are active at national, provincial and municipal levels across Europe. PMS enable the forecasting and prioritising of future maintenance budgets. They also enable the estimation of costs associated with delayed maintenance, and thereby assist in defining the consequences of variations in maintenance strategies.
For end users (road users), more efficient maintenance will lead to reduced costs, better and safer roads and less traffic congestion.
