Análisis comparativo de diversas especificaciones actuales sobre las mezclas asfálticas drenantes y su aplicación en las normativas colombianas

Abstract

Knowing that the pavement is the construction structure that has been used the most by man and occupies twice the area of ​​buildings (Karl M. Smith, 2016); For some years now, research has started to be carried out on the benefits and harms of a conventional pavement. Among the most relevant problems of a conventional pavement is the production of 2/3 of the excess runoff, the contamination of the soil by hydrocarbons, the reduction of infiltration by 66% and the increase of urban temperatures by two thirds. , known as "Islands of Heat". (Karl M. Smith, 2016). Additionally, they influence the hydroplaning of vehicles that travel at high speeds on wet pavement. All of the above, calls attention to the recovery of paved areas for the benefit of the biophysical environment and human beings, as well as to diminish each one of the road risks. Some of the solutions to these problems are porous pavements (PP). These are those that have integrated networks of empty spaces through which water and air circulate, which generates qualitatively different processes of storage, treatment and flow. It should be noted that PP materials are almost indistinguishable from non-porous materials in construction and surface appearance, but they have a significant influence on urban hydrology, rooting habitat and adherence between the tire and the road. In view of the fact that Colombia is a country with high rainfall and road accidents, the question arises. Can porous pavements be used in this country? Consequently, in the present work we seek to identify the missing points of the regulations used in Colombia for the construction of draining asphalt mixtures, in comparison with European regulations.
