What is it about?

Considerable growth in industrial activities and the volume of road transportation of goods have caused a need for allowance of heavier lorries on the road network to make the road transport more economical. In this study the increased effects of traffic load on infrastructure is assessed with monitoring and simulation model.

Why is it important?

The characteristics of traffic load are important to know in design of safe and sustainable structures. The increase in allowed gross vehicle weights in legislation have certain increasing effect on live loads for example on bridges. Therefore the design loads need to be recalibrated according to present legislation.


During this research the personal knowledge about the backgrounds of calibration of traffic loads and design principles of bridges and especially loads, was gained significantly. It was also interesting to see how the change of allowed vehicle weights in road traffic effects on monitored loads on bridges.
