Evaluación de mezclas asfálticas en frío con RAP estabilizadas con cal hidratada y cemento

Abstract

The accelerated growth of cities, as well as of the population, increases in parallel the demand for resources to meet the needs of housing, work, recreation, among others, which require a good transportation system. Although the Ministry of the Environment, together with the Ministry of Transportation, is currently making more intrusive allusions to green infrastructure and the modes of transportation to which we must migrate for a more sustainable environment, we cannot leave aside the systems that we already have to move from one place to another and that require urgent attention for their maintenance and rehabilitation. In this sense, this document will deal with the proposal to make a new use of materials that have already completed their first life cycle, as it has been done since the 50's in Europe and North America; applied to our region with special characteristics due to its climatic behavior. It should be noted that this is not the first study carried out in the country, and that scale applications have already been carried out on roads in the cities of Bogota, Medellin and San Andres in order to evaluate their behavior; however, the scope of the proposal is to contribute to the bibliography of this technology for a cold mix added with virgin aggregates and for use as a wearing course, different from the studies mainly carried out on hot mixes.
