Questions from readers
Do you design for heavy trucks?
Yes. Pavements are designed for the axle loads we measure on site, not national averages, which matters on industrial and port routes.
Can you manage traffic during the works?
We prepare the traffic management plan and agree it with the road authority before work starts.
