The material that decided upon for the protection layer was vinite or reinforced rubber mat,
which is a very tough, flexible material. This layer, the green layer illustrated in Figure J.9 and
Figure J.10, should only protect the briquette from the abrasion of the wheel, with the intention
to minimize loosening of aggregates in the surface of the BSMs. A test was carried out with the
vinite protecting the specimens and after 100 000 load repetitions the cover and surface were
still in perfect condition. The grey path noted in Figure J.10 is result of the green colouring
wearing off through abrasions by the wheels.
