RESUMO

The objective of this research is to demonstrate that crushed stone has a significative variation in price from the quarry to its final use. Most of such increase is not related to mining activities but to logistics activities, mainly physical distribution. This variation is highly intensified in conurbations and big cities such as São Paulo, where there are traffic restrictions to cargo vehicles. The circulation in certain areas at determined times being prohibited due to the municipal number-plate alternating system in specifying types and sizes of vehicles, generates a need for a larger and more diversified fleet, not to mention more personnel. Besides that, there is underutilization of the fleet because of the days, time and places of restrictions provoking more traffic jams and pollution rather than eliminating them, which is exactly what is desired. Traffic jams due to the aging of the fleet in use, once the companies have incorporated used vehicles to compensate for the municipal number–plate system. Being in use for long such vehicles frequently breakdown on streets and avenues thus impairing the traffic. Pollution is caused by old engines that besides more fuel also burn lubricating oil, not to mention the traces of oil leaks left on public streets and avenues. Such burden is left for the final consumer to carry by spending more money waiting longer and having to adapt to the time authorities offer now with a new legislation in general at night.
