Asphalt Aggregates

This type of products are mainly used in roadworks, either urban or intercity. Hot mixed asphalts use aggregates produced in dry condition, differently than the aggregates for road surface treatments, which must be washed and generate wastewaters.

Up to date in Chile there are no national codes for aggregates used for asphalt and they are governed only by recommendations of the Manual for Roads of the National Road Direction and the Regulation Code and Technical Specifications of the Ministry of Housing and Urbanism. That is why the Najar Group have developed a great number of studies and technical publications in Chile and Latin America concerning the subject, to submit proposals on how such products could be regulated.
