A century or more ago, building roads was a time-consuming business. Bullock teams hauled stone road rollers one way, then the other, to compact the earth. Corrugations on the rollers maximised the pressure.
Infrastructure like roads is very important to the wellbeing of a society. In Australia goods are often transported by road across the country. However, wear and tear caused by heavy vehicles means roads need constant, expensive maintenance. Rail could offer a good alternative as fuel prices rise and road transport becomes more costly.
