Improvements are being made on the stretch of Route 3 between the city of Trinidad and Paso del Puerto. The work done by the consortium INCOCI-Cujo is running a retreading concrete using the technique of whitetopping attached.

In a total of 52km a concrete layer thickness 14cm on the existing pavement asphalt will tend, which previously receive the recoating is milled to recompose the transverse profile, texturized to ensure adhesion with the new concrete, hidrolavada and swept with compressed air.

The consortium is responsible for the whole process: grinding stone, sand extraction, design and manufacture of the concrete mix, transportation, laying, and curing joint sawing.

Regarding the concrete paste, it is a mixture of 5MPa characteristic flexural strength, containing microfibers and macrofibers polypropylene, which gives the material strength values of plastic cracking and toughness which naturally has, reaching develop a minimal residual resistance 1MPa after having fissured by reaching its breaking strength.

To date, it has already paved 10km, and it is expected that the entire section is completed within twelve months. In banquinas a layer of granular material and subsequently CBR80 double bituminous treatment will be placed. new signaling is also installed vertically, and the horizontal signal will voiced edge.

Bitafal group participated in the "Technology Days" Wirtgen Group.

In last April, Bitafal group He was present once again in Road Technology Days del Grupo Wirtgen in Germany accompanied by a large Uruguayan delegation.

During the nine-day trip, they visited industrial plants in various parts of the country of diverse types, from manufacturers to crushers spades, then witness this great biennial event of RoadTechDays.

There is no doubt that the Wirtgen Group after its acquisition by John Deere, will be the most significant company for the category Paving the world. The event is organized living testimony to this, showing that the German perfectly together with American affluence produces an admirable formula.

We prior to this stunning event Wirtgen, with strong Uruguayan presence of colleagues Molisur, Serviam, Hernandez and Gonzalez, Traxpalco and CVC, met plants Wirtgen, Kleemann (shredders) and Betek (spades for recyclers and milling machines) for 3 days.

Then we transladamos south to the small town of Ludwigshafen, where modern production plant of Vögele, which would be held the RTD is.

During the two days of the event, all kinds of compactors, recyclers, milling machines and finishers were displayed. Then they had techniques of each of the aforementioned companies and live demonstrations of how each of these talks.

After the event an artistic representation of machines with dancers and acrobats was done in a real show of power, lights and fireworks. In the video shown below have a more detailed description of the event.

Thank again the people of Tradinter Y Grupo Wirtgen by the organization, dedication and treatment, which make this a repeatable and recommendable experience.

CITEVI gives a great step incorporates a Rheometer (DSR)

We are pleased to inform our readers that we are adding to our Research Center (CITEVI) Court Dynamic Rheometer (DSR for its acronym in English).

In a natural evolution of a company committed to the development of national road company, it's time to incorporate a computer that involves a before and after in the knowledge of the binders we handle.

This sophisticated equipment allows to know the performance of asphalts much of its viscoelastic range. Mainly we are concerned in these latitudes, that is at medium and high temperatures.

The team selected after several months of visits to research centers in the region and the US, is a Anton Paar SmartPave 102 with all accessories to perform the usual tests standardized by AASHTO and other agencies both America and Europe.

It is expected to be operational by August so we'll have more news on this in future editions of this Newsletter.

surface treatments and winter

Reviewing the notes from previous years, we are When winter with a recurring theme. The gravillados in winter and care must be taken to prevent landslides.

This year is no exception, exactly the opposite, there is more surface treatments works underway in all previous years and landslides came in several of them.

Como siempre, la primera culpable es la emulsión, que es exactamente la misma que se usó días anteriores, con 10 o 15°C mas y no hubieron inconvenientes. Debemos entender que la veda que dispone el Pliego de Vialidad tiene su fundamento técnico en evitar estos desprendimientos si se trabaja de forma “tradicional” ya que las condiciones de curado de las emulsiones se ven seriamente modificadas con el frío.

Moreover, we note with pride that works in which they have implemented multiple treatments Latched (TMT®) and has been used exactly the same emulsion in defective works, do not have a single stone detachment.

We leave the note describing best practices to avoid problems of landslides in winter: SEVEN RECOMMENDATIONS FOR USE OF EMULSIONS IN WINTER

We recently implemented TMT® in several plays and come behaved very satisfactorily. We can highlight a stretch of Route 23 and Route 94 by Eduardo Martinez, also CVC on Route 8 and Route 96. Cujo in All these works were carried out with emulsions in May and have had no problems.

For more information about running TMT® contact our technical department on 0800 8425.

We attach some photos of the above sections.
