Sustainability

Advantage 29

Only the necessary pavement thickness depending on traffic and the climate must be applied to get a durable, cost-effective and sustainable road.

In Belgium, for a major highway (Class B1), the thickness of a concrete road and an asphalt road will be similar, but for lower traffic category roads (Class B5 and even B9) there can be larger differences. With a concrete pavement, the structural thickness will never be less than 180 mm, whereas with asphalt a lower minimum may be used either in staged construction or for lower volume roads.
