used in the construction of our roads. The rock type has to be carefully chosen so that it has suitable properties for the job it has to do. Pupils are asked to work out which rocks are the most suitable for use as roadstone aggregate. Show pupils the diagram of the cross section through a road surface (below) and provide them.
Dolerite, an igneous rock, is exposed over half of. Tasmania. The good physical and chemical properties of the rock make it suitable fora wide variety of uses. Crushed rock is used as aggregate in concrete, as road sub-base and in flush seals, as facing stone in building construction, and as armour stone and rip-rap.
