Fabricación de hormigones asfálticos tibios en el Ecuador.

Abstract

Considering the environmental contamination of the asphalt mixtures technologies have been developed to reduce working temperatures to save energy, lower emissions and a higher level of safety on site. In order to do so, it is proposed the manufacture of warm asphalt concrete in Ecuador, with the aim of developing the warm asphalt mixtures to reduce the mixing and compaction temperature, modifying the asphalt viscosity.

In most of Europe and the United States a series of technologies have been used, in this work carnauba wax is used as a viscosity reducing additive.

This work was done experimentally in the laboratory, achieving satisfactory results regarding the performance of the warm asphalt mixture compared to hot mixtures.

Based on the above, it can be concluded that carnauba wax is a viable option to reduce the viscosity of the asphalt at lower temperatures and can be used in the production of asphalt mixtures.
