It is a common practice in the country to place asphalt layers, one on top of the other in many of the interventions on streets, avenues and roads failing to observe international standards such as milling that guarantee the original design of the road corridors.
The level of elevation of the roads is higher than the containers and sidewalk, which makes it easier for drivers to climb onto the roadways or for the storm drainage system to overflow and puddles to form more quickly that deteriorate more with the passage of vehicles. speed the asphalt.
Over time, what is called exudation in engineering occurs, caused by excess asphalt and at the same time wear of the surface that makes it difficult for the tires to grip. In some cases the placement of an asphalt layer on top of the existing one, without the millingaims to save the budget allocated for certain works and for speed.
In avenues such as Winston Churchill, Abraham Lincoln, 27 de Febrero, Máximo Gómez, José Núñez de Cáceres, Simón Bolívar and others, unevenness of the bearing space can be observed with the walk of pedestrians and the containers, which must be higher to facilitate drainage and protection for pedestrians.
When vehicles, for any reason, fall between the very high pavement and the container, the damage to the front axle and the crankcase is serious.
The Vice Minister of Supervision and Inspection of the Ministry of Public works, Roberto Herreraconsiders incorrect the practice that has been maintained in all governments, including the current one, although not in all works.
Explain that a asphalt It should last between five and eight years, depending on the quality of the material used and the use of the track.
“We have really had a lot of concerns about this issue, it is not a very complicated issue… what happens? Sometimes the authorities, the governments, have several options, many times what is done is that a layer is placed on top if the level allows it, other times due to speed this type of error has been made, which is not an error if the level of the content allows it.
Consider it a mistake that the asphalt of the road exceeds the level of the sidewalks because it affects the correct channeling of water, in short, “that is an undeniable practice, it cannot be denied by past governments or by this one that there are times when it has been incurred in that mistake of placing a asphalt over a layer that had to be milled that had to be removed.
He assures that the current authorities are preventing this from continuing to happen and are requiring contractors to place the new asphalt layer after the milling that has ended its useful life due to wear and tear.
“The instructions are in place so that this practice is not continued not only in this government, but also in others and that part is not carried out. Now a good part has remained, many streets of the city with that inconvenience you see the level of asphalt above what it should be.”
Clarifies that the Ministry of Public works pay contractors for asphalt that they place, aware that the road can withstand an overhaul and based on that they are paid, so they understand that there is no deception of the State.
Herrera explains that one way to save money is to implement a technique that is reheating the asphalt layer and reusing the material by placing an additive that ensures the consistency of the road and that represents economy that is applied in various types. of projects.
