DACH – Research project – Durability of porous asphalt pavements (VSS2007/501)
Overview
Background & policy context:
The construction of porous asphalt pavements experienced a recent technological development in Switzerland, in Germany and in Austria. The advantages of this type of pavement lie primarily in the disappearance of the aquaplaning risk and the noise reduction. However, certain disadvantages are raised like the reduced lifespan of these materials in comparison with traditional pavements, as well as the winter maintenance which can be difficult sometimes.
Objectives:
The aim of this project is to describe state of the art of the developments and the experiments relating to porous asphalt in Switzerland, Germany and Austria. With the initiative of the road Directors within the CEDR of the sectoral research programs are engaged among several countries sharing the same concern.
It is proposed to establish an inventory of the porous asphalt pavements existing in these three countries. With this intention, a very complete questionnaire was made and was distributed to the regional road administrations. The data thus collected could be analysed and evaluated. A report will make the critical synopsis of the collected results. The bases for a possible international research program will be thus established.
Methodology:
The methodology of the project is as follows:
- bibliographic research
- surveys through a questionnaire
