Abstract (en)
The road surface, comprising a base layer (2) and an upper layer (4), has at least one intermediate layer (3) with a high level of cavities to allow for the removal of heat by ventilation. The base layer is rigid and 6-8 cm thick. The intermediate layer, 4-5 cm thick, is made e.g. from bitumen-bound gravel and sand with cavities comprising 25-30% of its volume. The top layer is rough and 2-3 cm thick.
