Impact of tire types and configurations on responses of a thin pavement structure

The objective of this study was to assess the impact of tire and tire configurations on the responses of a thin asphalt pavement structure by means of full-scale tests using a Heavy Vehicle Simulator (HVS). A total of six different types of tires, four single and two dual tire configurations, were investigated. The structure was instrumented to measure tensile strains at the bottom of the asphalt layer and vertical stresses and strains in the unbound base, subbase and subgrade layers. The results indicated that, in general, single tire configurations produced higher tensile strain at the bottom of the asphalt layer and higher vertical stresses and strains in unbound base, subbase and subgrade layers.

Increasing cycling among the elderly

Cycling is good both for your health and the environment. It can give you freedom and the ability to get out and about, not least for the elderly. But with age, it can become harder to choose your bike over your car. Maybe your fitness and balance are not...


VTI launches new research

VTI's ambition is to create cohesive maritime research in areas such as transport economics, logistics, environment, behavioural science, and navigation. One current assignment concerns the validation of research in a major international EU-project, Sea...


New study examines the mental health of seamen

Working at sea and being away from home for long periods can be mentally straining. In a preparatory study, researchers at VTI will examine how prevalent mental ill health is among ship crews in Sweden, and how the shipping companies' preventative efforts are...


Measurement of fatigue among bus drivers in London provides tools for better traffic safety

VTI has participated in a study of fatigue among London bus drivers. The study has given Transport for London the tools to implement measures that deal with fatigue among the city’s bus drivers.
