In September 2009, a consortium of 12 partners started to develop a durable, safe and extremely noise-reducing poroelastic road surface (PERS). PERS is a novel pavement type, containing a substantial amount of rubber (new or recycled, e.g. from scrapped tires) and an elastic resin (like polyurethane). The work is carried out in the framework of the PoroElastic Road Surface for Avoiding Damage to the Environment (PERSUADE) project and has the financial support of the European Commission (EC).

The project duration is 6 years, and in the first 3 years, the main focus was on the development of a mixture with a number of criteria: a high noise reduction, a sufficient raveling resistance, a sufficient binding to the sublayer and an acceptable drainability. The research of the consortium involved the testing of numerous samples with a variety of laboratory tests and led to two promising mix formulas. The consortium has started with the construction of five "full-scale" test tracks in five different countries and these tracks will be monitored. The PERSUADE project includes the study of environmental and economic aspects.



Cost Benefit Analysis (CBA) workshop in Stockholm

An open seminar and workshop in Stockholm will be held on 25-26 April 2018. The workshop deals with the use of CBA as a basis for decision-making in the public sector. The workshop is organized by, among others, Professor Jan-Eric Nilsson, VTI.



Modal shift for an environmental lift?

Investigations in Sweden and other countries suggest a shift of goods transport from road to rail and waterborne transport to reach environmental and climate objectives. VTI is leading a new project to investigate how the modal shift can contribute and what...


Automation and digitalisation are making rail competitive

Road transport is developing rapidly and its productivity has increased sharply. Rail transport, however, has not developed at the same rate. Automation and digitalisation are essential if rail freight in Europe is to survive.


New research is creating a driverless logistics chain

The research project Born to Drive has come up with a system that allows new cars to move, without a driver, from the production line out to the parking area prior to being transported elsewhere. The vision is to automate the entire logistics chain from...


VTI testing automation in EU project

VTI is leading a series of tests in a major EU project on automated driving. The first driving tests were carried out n a test track in Slovenia in December. The project will focus in part on acceptance among different groups in society, in part on...


Freight transportation on road and rail analysed

Freight transport accounts for a large proportion of the emissions, noise and congestion produced by road traffic. Transporting freight in larger but fewer lorries could reduce the problem. At the same time it might entail freight being diverted from more...


Millions for research into maritime transport and the environment

Maritime transport is a major source of emissions of harmful air pollutants and carbon dioxide. In a new project, a research team from the Swedish National Road and Transport Research Institute (VTI) and the University of Gothenburg has received SEK 6.4...
