The costs for the production of recycled aggregate concrete from old concrete pavements must be contextualized in the works for road paving in the country. Values provided for urban roads works may not reflect the specific conditions of the demolition on highways. Also, prices operated in other countries are affected by the recycling technology used abroad that is not what has been used in Brazil. In this article are considered the unit production rates related to demolition, loading, transportation and crushing of concrete pavement removed from two Brazilian highways. Based on the results it was verified an increase of 50% in the final cost of the recycled aggregate compared to virgin aggregate, resulting in an increase of about 20% in production costs of concretes for paving. The Brazilian potential of production of such recycled aggregates is limited what can be a stagnant factor for the use of this technology in the country.Downloads
