Abstract: A spacer for fixation to a construction element, for maintaining a relative distance to another construction element, and for restricting at the maintained distance a movement about a position that is relative to another construction element, the spacer having a structure that: a) provides resiliency and generates a force for enhancing a distance relative to another nearby construction element when distance to that other construction element is reduced to a predetermined distance, and b) provides restriction of a movement of the structure in at least one direction that is different from the direction of predetermined distance.

Abstract: A system for assembling a road comprises a plurality of plastic support structures and a plurality of road deck elements. Each of the support structures comprises a base plate and at least one column extending, or for extending, upwardly from the base plate for supporting at least partly one of the road deck elements. Each of the road deck elements is configured such that in an assembled and as road useable condition of the system rainwater predominantly flows away over the road to one or more positions next to the road, and/or to a slit-sized interruption of the road across the road.
