Alternativa beläggningar – högpresterande: kunskapsöversikt


Knowledge and experience in high-performance asphalt mixtures, such as polymer modified/rubber modified bitumen etcetera can lead to increased pavement service life. It would mean a saving of natural resources and construction and maintenance costs. High-performance mixtures, or using new structures could therefore be an alternative for the client to achieve the targets the government and parliament have set up. The goal was to demonstrate the benefits of sustainable mixtures from an economic and environmental perspective. The overall project includes both the acquisition of knowledge in the field, suggestions of alternative designs and high performance materials, implementation and demonstration of recent knowledge, use of reliable deterioration models and functional methods for the design and development of roads. Models and methods are valuable to create favorable conditions for the implementation of newly developed products. The conclusions from this limited overview is that there are high-performance asphalt mixtures and technologies that can lead to longer service life of roads in addition to conservation of natural resources. The concept can also mean lower costs and less environmental impact.

Vehicle Driver Monitoring: sleepiness and cognitive load

To prevent road crashes it is important to understand driver related contributing factors, which have been suggested to be the critical reason in 94 per cent of crashes. The overall aim of the project Vehicle Driver Monitoring has been to advance the...

Crash testing bicycles at VTI

For the first time single bicycle crashes have been simulated at the VTI crash safety laboratory.


A case study exploring firefighters’ and municipal officials’ preparedness for electrical vehicles

A VTI-study presents a social perspective on new vehicle technology. It explores the self-reported preparedness of the fire departments (i.e., rescue services) in Sweden’s three largest cities regarding rescue operations involving electrical vehicles (EVs).


Pioneering research on and about bicycles at VTI

Under what circumstances might cyclists lose tyre grip? What actions could then be taken to prevent a crash? VTI is currently developing a theoretical model of the behaviour of bicycle tyres during braking and steering in different situations and on different...


Virtual pedestrians create efficient stations

If more people are to choose sustainable travel, then the public transport stations of the future must be designed so that pedestrians can get where they are going quickly, without congestion or queues. The Swedish Road and Transport Research Institute (VTI)...
