We are finishing the resurfacing of the double carriageway(driveway resurfacing)

The recovery work on the climb route of the Southern twofold carriageway includes 10 kilometers Southern, inside which seven viaducts were recuperated and progress is being made in laying the pavement in the remainder of the through, action that is at 85%.

We are at present doing the last resurfacing work at explicit focuses that will go on until the third seven day stretch of November, and later we will complete the flagging exercises between the first and second seven day stretch of December. Work days are planned from Monday to Friday between 7 am and 5 pm and from 7 pm to 5 am; and on Saturdays from seven AM until one in the evening. During top hours we empower the rising to two paths to ensure liquid portability out and about.

A safe and comfortable route for users

The renovation process of this hallway is intended to build up the black-top design made out of two layers: the primary (MAM 25) with a thickness of 10 cm and the last moving layer (F13) with a thickness of 3.5 cm, consequently ensuring the safety and solace of the users who travel along this route with sufficient specialized conditions.

During the process of laying the pavement, two issues emerged at explicit focuses that impacted the underlying plan for getting work done:

Detriments gave the black-top blend, which didn't have the normal conduct in the wake of being applied in the space Southern, for which a quality examination was needed to confirm that it followed the set up specialized boundaries. 

In said investigation, issues with the totals of the combination were confirmed, which constrained us to settle on the choice, along with the examining and the worker for hire, to eliminate it and repave it, to ensure the length of the design of the pavement.

At first, we did the intercession between the Alto traffic circle and the entry to the La Esperanza town, and presently the works are being completed between the La Esperanza town and the La Barraca bend. This process doesn't create any additional cost for the Government of Antioquia and is completed inside the assurances of the undertaking.(concrete driveway cost)

Notwithstanding the abovementioned, we completed an assessment of the old base of the current pavement, wherein issues were clear in its construction that impacted the nature of the new pavement. 

This required overhauling the base construction and introducing a geocell (a framework that permits great compaction of soil and different granulated materials) nearby between El Zarzal and La Barraca bend, fully intent on improving and backing to said structure.

Night exercises

Around evening time we execute the processing or expulsion of the current black-top layer to be paved the following day. At the point when the pavement is eliminated, the mediated area is handicapped for the travel of vehicles until it is paved.

For what reason isn't the whole resurfacing process done around evening time?

To ensure the nature of the materials and that the works consent to the specialized boundaries, the clearing process should be completed around the same time so the pavement and encompassing temperatures are ideal, since these can be exceptionally low nearby. .

At the point when the process is done under deficient conditions, it can cause lacks in the nature of the blend and in the completion and toughness of the black-top, added to this around evening time it is difficult to do a severe management of the process, which would cause reprocessing in the undertaking, at last affecting the all out span of the work.
