What are the treatments Multiple Trabados®?

The TMT® are an innovative way to run single and double treatments, which improves the mechanical interlocking of aggregates and minimizes risks of landslides.

Its development is linked to the use of emulsions it allows full coverage of aggregates and which differs from the conventional methods as applicable.

They can be run at any time of the year and on any surface, allowing traffic early release with conventional methods than aesthetics. Success depends on the type and quality of materials in conjunction with the proper technique. It is ideal for initial treatment of stabilized bases technique.

The TMT® They are the product of several years of observation and continuous improvement of construction procedures with laboratory research, new product development, development plan and implementation on site.

HOW DOES IT WORK?

It involves placing the right amount of binder and aggregate at the appropriate time and place, saving up to 20% of materials.
optimum mechanical and chemical resistance is achieved by the way it is run, accelerating the curing process and accommodating the stone to ensure detachment almost zero.
The method includes a number of key intermediate steps substantially increase the adhesion between the aggregates.
aeration of the emulsion is favored, allowing further exposure to external agents which accelerate curing.
Find your best performance with the use of modified emulsions.

SOLVE WHAT?

Gravillados building permits at any time of year.
Accelerates the speed of work, allowing progress without risks.
Minimizes landslides and prevents excess aggregate causing damage to the windshield and risks to users.
It requires fewer passes fracture mitigating Compactor aggregates and prevents its removal from the use of this equipment.
It does not require subsequent scan, nor tire compactors to settle the stone.
It allows controlled traffic before the system has completely healed rating.
The final quality of the surface obtained is smooth and silent, with better contrast for roadway marking.
All jobs are completed in a single workday, allowing high yields.

BITAFAL present in the Circulars Opportunities Program

On Wednesday morning, August 8, 2018 the Teatro La Colmena opened its doors to welcome the fifth, and final, meeting dedicated to BUILDING OPPORTUNITIES PROGRAM CIRCULARES.

This is an initiative coordinated by ANDE and biovalue (together with MIEM, MVOTMA, MGAP, UNIDO, GEF and supported by Transforma Uruguay and ANII) to promote joint actions and thus promote the creation and implementation of sustainable productive projects, the framework of circular economy.

We had the pleasure to share a morning full of information and where BITAFAL presented the progress in the use of modified asphalt powder neumátuco out of use for road construction in Uruguay.

At the beginning the basics and regional and international examples of circular economy by the Coordinator of the Environmental Engineer biovalue María José González were presented. Then the Coordinator of associativity area and Integration of the National Development Agency (ANDE) Economist Paula Cobas presented the convocation of Circulars Opportunities Program.

In the second instance it opened a "Living" questions of the problems and opportunities in the construction sector in the transition to Circulate Economy, moderated by Giselle Della Mea (3 Vectors - Innodriven). With Architect Eduardo Siuciak (FARQ- UdelaR) and Ing. Jorge Pazos, Executive Director of the Construction Chamber of Uruguay.

Finally, a panel of businessmen and entrepreneurs with national and regional experience was convened to make a "double click" with examples of application of circular principles in their respective businesses and areas. The exhibition began with Robert Pacheco (Argentina), founding partner of EWAR, a company that since 2008 began to venture into the production of biosynthetic wood boards. The Qco Santiago Kröger (Uruguay) continued presenting the benefits, development, application and prospects of incorporating disused tire dust into asphalt cement. Next, Eng. Nelson Siqueira Nieto (Brazil) from the company RNV Residuos, presented on recycled aggregates, as a sustainable and cheaper solution than the use of non-recycled aggregates. To close the day, Arch. Eliseo Cabrera presented "La Casa Uruguaya", a winning project of the National Prize for Energy Efficiency - Cat. Buildings 2016.

From BITAFAL Group we appreciate the invitation as exhibitors to count the work we have done after collaborating with the environment and society. We welcome these instances of exchange opportunities to further develop new ways of doing things, with a more systemic vision that includes all parties are generated.

In the next LINK We share the presentations made on that day. ()

On the website CIRCULARES OPPORTUNITIESThey may elaborate on the call and the different activities and workshops that have been made under the program.

11th CONGRESS OF ROADS URUGUAYA

Last 8.9 and 10 November LATU received more than 350 players in the Uruguayan road in its biannual Congress.

He Bitafal group thereof he participated in the exhibition with an innovative proposal to know who work every day to be "Strategic Suppliers of his work". Also, from the technical point of view, we have a novel stereomicroscope for quality assessment emulsion was presented.

We participate in technical presentations 3 Qco works. Santiago Kröger with colleagues of national roads within Block Pavement and with the presence of several of our partners as Congressmen.

Congress had several new features such as new commercial exhibitors, including a section on the outside for big teams and presentation of technical papers by e-posters mode.

The opening of the Congress was in charge of the President of the AUC, Ing. Gisele Pingaro, the Minister of Transport, Víctor Rossi, Director of Mobility of the IMM, Pablo Inthamoussú, the Director of LATU and IDB representative for Uruguay.

After the opening ceremony, Eng. Juan Campana, Director of Engineering Argentina National Roads Authority, held a conference on "The new management National Roads Authority of Argentina: technical update" showing great work being done in the neighboring country roads.

Within the thematic blocks, more than 30 technical papers were presented on Transport, Road Safety, Structures, Management and Maintenance as well as floors.

He BITAFAL group He participated with three technical papers on "Evaluation of membranes SAMI after 7 years in service", "First stretch of asphalt rubber mixes warm in Uruguay" Y "Evolution of a stretch stabilized with cement" with interesting findings on each of the technologies applied.

Conferences were given by Ing. Boris Goloubintseff (IMM) "State and Status of Mobility Management Center, a year of its implementation and operation", Francis Pumares in Spain in Block Road Safety "Certified Barriers", Ing. Shlomo Liberman of Israel "Bridges of prestressed continuous beams" and Dr. Ing. Luis Guillermo Loría of LANAMME of Costa Rica with two Conferences "Application performance testing design blends" Y "Evaluation of rheological properties of modified".

Besides a round table held on "Road Maintenance" where different visions 20 years of the first CREMA contracts with participants by the MTOP, contractors, and consultants were exposed IDB.

At the close of Congress there was a special session on the new edition of the Book "Status of Roads Uruguaya"After almost 14 years without being edited and awards to the best works by Block.

A distinction was also awarded as the best work of Congress "Bowstring arch bridges across the board" Ing. Fernando SACEEM radio, over bridges made in Tacuarembó Paso del Bote where BITAFAL Group actively participated in some of the same innovations as waterproofing membrane anchored board and neoprene seals as reported in Bulletins #78 Y #80.

The exhibition was varied and new companies participating in it. The new addition was the outdoor exhibition with displays of equipment.

We hope that the next edition still loaded with new features.

IMPROVEMENTS IN ROUTE 81

INCOCI RENTALS BITAFAL trust for the execution of a stretch of cold recycling on site.

They are making improvements to Route 81 in the section that connects the new bridge over the St. Lucia. Once the works are completed there will be a corridor between Route 11 and Route 5 giving it the importance it deserves the new bridge and bypaseando St. Lucia and Canelones substantially improving travel times.

The work done by INCOCI includes an expansion platform, recycling of the existing macadam, performing an offset Portland cement stabilized layer and a concrete floor 21 cm.

For the implementation of recycling and stabilized base, BITAFAL RENTALS He collaborated in the dosage of Portland cement, recycled walkway and initial compaction.

For widening of the platform teeth on both sides of the existing roadway is made with successive layers of granular materials CBR 10, 40 and 60. A cement stabilized granular layer remaining flush with the existing roadway is then executed for have similar rigidities.

Across the width of the new roadway a regularizing layer was made. To do recharged with crude which was then stabilized in place by adjusting the dosages of cement according to the thickness profile. At this stage of the existing recycled macadam. For thick thicknesses were made was fundamentally a heavy compaction equipment kickstand to achieve densification.

Currently running the concrete pavement 21 cm thick is achieving very good resistance values and excellent surface finish.

INCOCI thank the confidence provided BITAFAL group.

COMPARISON OF STABILIZATION OF ROADS TECHNOLOGIES

GROUP BITAFAL was invited by the OPP to participate in a comparative experimental section of stabilizing products in the Constancia in Paysandu, seeking to know which of them could ensure durability in rural roads.

Of the 11 kilometers of road thousand meters were left at each end as witnesses, which is not an application is made, while the remaining 9 kilometers are divided into 6 sections and each of them will be a specific application (SEE: LINK SITIO PAYSANDU.GUB.UY)

BITAFAL group It will implement the technology introduced in Uruguay in 2013, stabilization on site with Portland cement in a length of 1500 m by 6 m wide. The other stabilizers are applied based on polymer, of ionic and sulfur.

It's an interesting experience to evaluate the performance of a large portion of existing stabilizers on the market, where quality, durability, the manner of execution and of course the actual cost of each in similar conditions will be.

En una reciente entrevista en El Telégrafo, Rodrigo de Souza, de la Dirección de Vialidad de la Intendencia de Paysandú destacó la “importancia clave de la prueba, hace años que se viene considerando la posibilidad y ahora la OPP ha decidido impulsar un cambio en la manera de mantener los caminos rurales. No hay dudas que el tránsito ha variado sustancialmente y que entonces es de orden que hay que promover el uso de mejores productos”.

Moreover, the Director of Works of the Administration, David de Lima said "This is a beginning, an experimental pose, but clearly we intend to carry on using these products, those that give better results in our soils. Within rural road recovery plans will be much more expensive at first but cheaper in the end. "

The project will have several controls. On the one hand, of the companies that sell the products, they expect to be applied in optimal conditions. Then the quartermaster. Third, the OPP. And besides, the Faculty of Engineering, which will closely monitor the work.

Scientific support will be key, because control of such stabilizers involves systematic chemical and physical-mechanical tests (SEE: NOTE THE TELEGRAPH September 2016)

SUCCESSFUL APPLICATION RECYCLING ASPHALT WITH FOAM

We can proudly say that the Uruguayan road has become unrivaled in the last five years. The design engineers have proposed and accepted new technologies, builders have art equipment incorporating the first world countries and we are encouraging, but we shake the pulse, to innovate.

Who would have thought that in our country the technologies to be introduced as modified asphalts based massively?

Who would have thought that the surface treatments and micros with modified asphalts would apply on routes first order?

Who would have thought it stabilize soils with continuous and mobile equipment was to be imposed so quickly?

Only the technical results obtained are certifying all these advances.

The most recent milestone of new technologies pushed him over the past year the company Hernández and González S.A. making a bet unmatched in his work of Route 3. Sparing no technical or economic efforts, the company conducted a site recycling pavement with asphalt foam backed administration. In last December he was terminated the reference work and drove around in full, being able to observe the same high quality in all its aspects.

an expansion platform a recycling of all of the existing road asphalt foam and asphalt mixture of 5 cm thick, several sections with widening of a third rail verges stabilized in situ with cement and waterproofed with asphaltic treatment was performed modified emulsions.

All this work was done in less than 100 working days. As we all know, when Hernandez is proposed, it does, but beyond personal effort, its staff and technology built in Germany show that can be reconstructed 34 km of a road completely new with a guarantee of over 20 years only 100 working days.

This is the reality we want to emphasize, if we want a Uruguay with very good infrastructure, we must use the best technology, the most productive and advanced end up being the most economical and durable.

This result is part of an innovation process together among the companies that participated in the Wirtgen Technology Days 2014 held in Germany, which agreed to bring in conjunction with H & G, Meliter, CVC and Tradinter a South African technician for the purpose of a conference the virtues of applying technologies foamed bitumen (Bulletin October 2014).

This process continued with the addition of equipment and technologies required for their application and hard work in laboratory design all involved. They were also required many hours of training, briefings and of course hard to successfully implement this advanced technology work in the country.

As anecdotario plus all innovations in this work, conducted jointly develop gravillados hot applied in July, during the winter closed season with a very good technical and result only applied at low temperatures in our country (Bulletin July 2016)

Reflections on state of emergency of national roads

Severe weather in recent months are to be felt in the national roads, from the primary network to rural roads(Source: El País, 04/19/16)

So much so that in several departments requested that the "emergency road" is declared, as indicated in Canelones (Source: El País, 10/04/16)and Salto (Source: El País, 13/04/16) as well as on the coast of the country (Source: El País, 04/20/16) And in the west in Cerro Largo (Source: El País, 05/09/16)

It has been announced by the government a battery of proposals from an extra small party for the Intendencias to cope with the deteriorating state of their ways to the extension of the scheme of PPP (Public Private Partnerships) to rural roads (Source: El Observador, 05/15/16)

He also spoke of a Strategic Plan for Rural Caminería (El País, 05/04/16) But without going into more detail than that is going to make a "Analysis of the needs of each department and introduction of new technologies for road construction".

PROPOSALS

In this aspect, from the Bitafal Group to continue innovating bet in real technical solutions for the durability of rural roads.

1) As We introduced in 2013 technology Soil Stabilization and Pavement Recycling siteToday we remain committed to expanding its use with new binders and execution techniques. We have Foamed asphalts as BITAFLEX AME which can extend the working range during cold periods and give improved performance of mixtures.

2) As ferrous Surface treatments advocates we are, we are developing new asphalts, emulsions and execution techniques to achieve higher durabilities at lower costs. Also looking to expand the range of work during cold seasons.

3) We continue spreading the use of both techniques together. Road engineering worldwide considers that the implementation of these two technologies is the ultimate solution for rural roads and not to mention, because of our scale, which for much of our crumbling road network. What we have learned we must communicate why We participate in conferences and seminars at national and regional level.

4) We continue to learn to apply in UruguayAs we reported in the last edition of "Making Roads" we learn from the Kiwis who have already worked hard to seek durable and economical solutions. One of our technicians will participate in a course Surface Treatment in New Zealand and now we plan to bring South African technicians to continue the dissemination of successful experiences in the world.

5) We continue warning the political actors about the risks of "new" soil stabilization techniques with chemical or biological products. El using these experimental technologies must be done in a progressive manner, and supported on objective, technically sound and consistent, which in one way or another, justify its use. For this test we participate in conjunction with experimental technologies, using the universal recognized technology stabilization Portland cement on a stretch of road in Artigas.
