And the possibility of higher-speed roads is not out of the question. Wayne Adaska, director of public works at the Portland Cement Association, says that as construction techniques improve and top size aggregates are reduced from the typical ¾ inch to as small as ½ inch, RCC pavement surfaces have become smooth enough for medium-speed traffic.
RCC is also used for pavements at composting and recycling facilities. The hard surface keeps recycled materials from being contaminated by gravel and soil, and it stands up to the heavy loads and punishment of the equipment.
American Iron and Metal needed a durable platform for a new metals recycling facility in Levis, Quebec. The company chose RCC for its low permeability, and was able to place the pavement and put the yard back into service within 72 hours.
