This corporate film shows the work of Dutch asphalt companies such as the Nederlandsche Basalt Maatschappij, NV Bitumenweg, and H.P. Vale Arnhem. We see the raw materials arriving by barge, the processing of these materials into the final product, and the different stages involved in paving the roads.
