Stabilisering av humusförorenad sand med hydrauliska och puzzolaniska bindemedel: resultat av förprovning och vägförsök: tillsättning av flygaska vid cementstabilisering av väg 1175

Laboratory tests, to treat a sand, contaminated with an active organic substance, with different hydraulic and puzzolanic binders, are described. Portland cement gave poor results, also with activating substances. Better results were obtained with a slag binder, activated with waste gypsum, calcium chloride, or a cement-fly ash binder.

A blended cement, containing fly ash, was used to strengthen road 1175 with a plant-mixed base-course. Because of the poor immediate stability, tests were made to mix in additional fly ash (a wet, conditional material). Good results were obtained and it was possible to decrease the cement content.

VTI contributes to study on older drivers and accidents

On behalf of and in collaboration with the Swedish Transport Agency, VTI has carried out a study of older drivers and the link between illness and traffic accidents. The Transport Agency has now published the results.


VTI in research programme Triple F (Fossil Free Freight)

VTI is part of the consortium that has been commissioned by the Swedish Transport Administration to conduct a research programme with focus on fossil-free freight transports. The programme, called Triple F, will run for 12 years. Part of the programme is...


Several actors collaborating on HCT vehicles

The increasing amount of freight, congestion on the roads and environmental emissions are problems that high capacity vehicles, HCT vehicles, can contribute to solving.


VTI’s simulators are being used for emergency vehicles

Better accessibility and shorter response times for emergency vehicles – this is something that standardised, directed, traffic messages, transmitted over the 5G network can contribute. Within the EU project Nordic Way 2, a functioning prototype of such a...


Modal shift - a way to achieve the environmental objectives

Shifting freight transports from road to rail and water can contribute to achieving the Swedish environmental and climate objectives by 2030. How this could be done is something that VTI researchers and researchers from Gothenburg University are investigating...


Report regarding government commission on the costs of traffic to society has been submitted

Since 2013, the Swedish National Road and Transport Research Institute (VTI) has had several government commissions to produce documentation on the costs to society caused by traffic. On 1 November 2018, the agency reported its latest commission, Samkost 3....
